in about 1987 i was a professional transmission rebuilder, i did that for 45 years, retired now. one day in 87 my younger brother had a 1968 Pontiac executive 2drht, i had never seen one, it was black and beautiful! he came to my shop and asked me, hey you know that wing nut that is on the breather? i said yea, he said what would happen if you dropped it down the carb. with the motor running? i said you didn't do that did you? he said he ran out of gas and was pouring gas into the carb. and it fell in! the engine was making a knocking noise on the driver side. i pulled the head and there the nut was as flat as a sheet of paper on no.1 piston! it didn't hurt the engine at all he passed away unexpectedly of a heart attack 2 months ago at 57 years old. he still had the nut in a jar. Billy you are missed little brother,,,,,,,,,,,,,,,,,,,,,
Had that happen with a vw beetle I had. It was banging so hard but it was my daily I said eff it and drove. All the sudden the noise stopped. Later disassembled and it had 13mm nut indentions on the piston. And when the noise stopped it shot into the muffler. Still ran great tho! Little 1600 vw motor ATE a full on 13mm m8x1.25 nut AmaZing. So a Chrysler should be able to eat a 5/8 nut Maybe even a 3/4!!!
Back in the '60s, spectators could walk right up to the paddock and pits at F1 races. I forget which race it was, but in '67, a fan had walked up to one of Brabham's cars in the pits during a Saturday qualifying session. Now back then, they were almost shoestring. Nothing like today with money being thrown around. They didn't have multiple engines lying around. They pretty much had one spare engine, and they swapped trans gears and rear gears as needed, and that was close to tuning and setting up for a race. So this fan walks up to Ron Tauranac as the story goes and chats. He sits on a rear wheel, and a stone pops out of the tread. They used heavily treaded tires back then. F1 was quite different. The stone pops out, and it goes...down a spark plug hole. The Brabham Team tried everything to get the stone out. Couldn't. They put the plug in, started the engine, the stone came out the exhaust as dust, and they qualified for the race.
You start the engine with the plug not in, and the debris gets blowed out the spark plug hole - kind of like with those crappy two-piece plugs used in Ford 4.6 3Vs. Plug breaks off in the cylinder, you drill through the remnants and thread in a stud for a puller. You also end up with some ceramic in your cylinder, and best practice at this point is what I stated above. With video, you can see the ceramic bits fly out of the cylinder!
Speedy dry does interesting things when poured down the intake of a lawnmower engine, while the throttle is tied wide open. Yup, after 2 handfuls slowly poured down the intake, I removed the plug and it looked brand new. As if it just came out of a sandblast cabinet or something. 😂😂
@@DanEBoyd It was some 4cyl pos, and since I was the newer guy the boss knew he was going to lose his butt, but he might as well save what he could. All 4 plugs snapped off , so we figured the best was to hammer the porcelain in. The threaded part turned in the hole no problem,but the carbon lip wouldn't let them come out. I threaded em in so they fell in the cylinder ,and proceeded to take a punch or 3 of different sizes and bust that thing into pieces on top of the piston. Took about 3 hours between hammering and using magnets and whatnot but it was successful.
I remember a while ago my son bought a little "pit bike" very popular these days, first thing he did was to make sure all the bolts were tight. Surprisingly enough they weren't. He forgot about the chain guide, low and behold it fell off after the first ride. This kind of reminds me of the old saying, " The bitterness of poor quality, lingers longer then the sweetness of a cheap price".
I got a Chinese pit bike, those dumbasses put the carb on the bottom of the engine with no guard, so if you high center the bike the carb is eating shit.
G'day from Oz, I recently bought an oil pump for our Holden v8, looked upon as a quality brand for as long as I can remember. I disassembled it to check it and cleanup the casting oil passages, I found machine shavings right through it and the end tolerances of the gears way to great. That would have destroyed a brand new engine, so to anyone check and recheck, it might take a bit longer, but it's worth it. Thanks Tony and your wife for your efforts, I am keeping an eye on you all.😉
After THREE different crankshaft position sensors from China left me stranded, I bought a NGK brand that says Made in USA. Now my 30 year old Dodge starts and runs reliably.
I went through three heater control valves in a ford ranger in less than a year before I decided to go with the Motorcraft. It would have been cheaper and much less labor and aggravation to have done that in the first place. Something about "Chinesium". It doesn't seem to hold up well with liquids, like gasoline, motor oil, engine coolant, water, you name it. If it lasts 6 months, you feel like you got a winner, until you find yourself at the parts counter a few days later.
I work on the production floor for one of the Big Three and have been with the company for 20ish years. We are seeing all kinds of problems with everything that comes from overseas, I've never seen anything like it. We are seeing 50% to 90% supplier defects, the supplier reps are saying that they are having to rework everything, especially the stuff coming from the Big Red Flag country. Rumor is that Detroit is telling suppliers to start bringing stuff back to the US. It's going to get crazy, and much worse before it gets better.
"You get what you pay for" applies here. I work in maintenance for a company that builds the electrical harness for GM, Ford and Mercedes. Different customers and different QC.
USA specs the parts. Its American companies ripping you off. If they payed and specified for higher quality, you'd get it, but they won't make as much profit off you. Let's be honest. Blame the companies asking for low grade big profit parts 👌
@@leviswranglers2813 I believe it! That’s one of the contributing factors to me getting burned out of the automotive industry and quitting last year. Ran a shop for 14 years. I’d had enough!
I am such an advocate for rebuilding sure stuff gets worn out but you can fix it, people have no idea the gold they throw away that carb, distributor or whatever it may be is so much superior in terms of materials alone
Yessir, happens to me all the time. I'm a vintage motorcycle restoration and repair service and I hear it all the time. Oh, I can get a complete new carb on amazon or ebay for 120 bucks! I proceed to tell them the factory original carb is worth between 400-900 bucks depending on the carb and the "quality" of the cheap carb will never come close, never mind performing anywhere near the oem parts. 😂❤
Bought a knock off china Autolite 2100 from Amazon a year ago for my 72 F250. Cost $84. Absolutely zero complaints. It worked so well I bought another one to keep tucked away.
The brass fuel inlet fitting on old Solex carbs for air cooled VW's is notorious for loosening after years of service. Especially when folks install a plastic filter inline between the carb and fuel pump. Heat cycles and vibration cause the inlet tube to fall out, while the car keeps running and the fuel pump keeps pumping fuel all over the engine compartment. Lots of VW's have gone down in flames this way. I pull that inlet, scuff it with coarse sandpaper, and JB weld it back into place. Never had an issue with it in 30 years of driving these old beaters.
An old short track racing superstition involves keeping peanuts out of the pits. The origins come from the small arenas used for midget racing where the pits were located beneath the grandstands. People eating peanuts would drop the shells which in turn found their way into the downdraft carburetors. How often this occurred is impossible to know but it happened enough that it became a long lasting superstition. Side note: I had an air cleaner tie down bolt break loose and fall into my engine. Destroyed the engine. Found the mangled up pice atop one of the pistons. I keep the bent piece on my key ring ever since to dispel anyone claiming it's an old mechanic tale.
Someone sends a Chinese company an original carb and asks it be reproduced for $1. That is the problem, pay more and get better quality but they’d rather have maximum profit
I've purchased quite a few Chinese knock off carbs for motorcycle, the first thing I do is take them apart , and inspect them and rebuild , I've seen where the casting needed to be filed so main jets fitted correctly.
Hey, it's not just the Chinese parts... I had a 1970-something Ford van we had converted to a camper. It had the 300 CI inline 6-cylinder in it. We had traveled all around the Western US and Canada with it. One trip from San Francisco Bay Area to Seattle, 2nd day out we're on the lonely stretch of I5 just over the Oregon border, there is suddenly a loud knocking in the engine. Oh crap! Luckily we have cell service and are able to call for a tow service. Our luck is still with us, the tow driver says we are just 5 or 6miles from Port Orford, Oregon where there is a Ford truck service shop! He's right! And, even better, it is a 60- or 70-year old shop, the type with all the machinery run off big belts in the ceiling. They specialize in heavy duty logging trucks, but were happy to help us with our camper van. Even let me do some of the work myself. Long story short, we pulled the head and found one of the little screws that held the bracket for the air cleaner had come loose and got sucked into cylinder #1. Minor scrapes on the top of the piston, but no real damage. We had to wait several days for a head gasket to be delivered, during which we had a really enjoyable time in the little town of Port Orford (five star restaurant, great accomodations, neat local history, unique tourist shops, winderful people). We had planned to just drive through, but thanks to the breakdown, we may have had the best 3 days of vacation in that quaint little town. Finally got the parts, learned that you could use metallic spray paint to seal a head gasket, paid a total of $260 parts and labor, and were on our way. Oh, and we put another 75,000 miles on that engine, which already had 150,000... and it was still running strong when we gave the van to our son-in-law for his painting business.
. . . so the upshot of your story is after several cross-country road trips, a screw (that hadn't been touched from the factory, I guess?) rattle loose & finally came off. That means its' actually a Chinese knockoff thing.
I bought a Chinese carburetor for a 1985 Suzuki FA50 moped that I snagged for free for the wifey many years back. No matter what I tried with the main jet I just couldn’t get it to stop 4-stroking - it was pig rich. Ended up having to drill out one of the air bleeds for the main circuit. Thing ran mint after that. Also bought a pair of 900W 2-stroke generators from Harbor “Fright”. Right out of the box, the carburetor was clogged with metal protectant. Then parts of the exhaust fell apart. Ended up having to go through the whole thing and tighten up every single nut and bolt. I can only imagine what the piston & rings look like. I didn’t dare look…😂
Thank G-- I found a NOS '73 BBD for my '72 318 Satellite on Ebay, On another note, rebuilt a carb on a 1985 Dodge Caravan 2.5 liter. Could only find three carb retaining nuts when re-installing the carb. Looked everywhere. Next day taking a test drive it was running like new, then lost power. The carb nut had fallen into a cylinder and it began to run on three cylinders instead of four after that. Needed to remove the head for a valve job. Combustion chamber was all scarred up but it survived to run another day.
Loved those old 2.2/2.5s!! Lost the head gasket on one in our minivan the saturday night we were moving.out of state. Short of time, I thrashed. Left the manifolds on and was able to do the job in about an hour... Van ran peachy for years after that. Sold it to a coworker who drove it many years further. Kinda miss it, five speed minivans are fun!!!😂😂
Things like this (and the fuel pump issue you had) are what makes me so nervous, especially on big jobs like the engine I built for my truck. And most recently the A518 transmission I just rebuilt for it. This is my first automatic transmission rebuild, so I am already nervous about my skills let alone the quality of the new parts. (Especially seals, servos, and electronics). I actually put it together and took it apart 3 times before I finally installed it. Just to double, triple check my work. I had alot of great help from the online community, many of whom are subscribers here. To all those that helped me, Thank you so very much.
I was a Hyundai/kia technician back in the early 00's I had a kia sedona minivan come in with less than 10k miles on it. It had a top end knock. Being they had a 10 yr, 100k warranty they said replace the engine whole. New engine came with equipped intake to pan. I swapped it out and sent it on its way. Kia wanted the engine obviously but I wanted to know why it knocked. I tore it down to find #2 cylinder had a tiny screw embedded into the piston. Further inspection lead to it was one of the many intake runner throttle blade screws. I had to make a report to the tech center. A week later kia came out with a TSB for the throttle blade screws. Ugh! That sucked. Thanks for sharing.
6:57 UT you must have a small block four barrel intake laying around the shop. Throw that thing in the garbage and put a 500 or 600 cfm edelbrock on it .
From my understanding, China can produce fine products if the American companies that are having them made insist on QC and supervise it themselves. If they just order the parts and accept what they get, the manufacturers will skimp on QC and save the dime.
I've got a '51 Farmall Cub tractor that I use around our place much like normal folks do an ATV. The body castings for the original carb were warped to the point they wouldn't seal with the gaskets. New carbs are unobtanium and used ones are an expensive gamble when you can find one. The Chinese knock offs are cheap enough but with a very bad reputation. I bought one with the idea of taking it apart and putting it back together with as many of the original parts as I could get to fit. The only original part that didn't fit was the brass fuel inlet fitting which had different threads. I managed to get a new fuel hose adapter that fit the new inlet and that thing runs like it came from the IH plant which has been closed for years.
With the cost of rebuild kits having gone into the stratosphere, these start looking much more attractive than a year ago. Thankfully Amazon returns are pretty painless usually to risk a China Carbonator.
Yes, when a simple 2bbl carb rebuild kit runs $70+ ! Stockpile used carbs that look serviceable. Just make notes on what they came from, junk today/gold tomorrow. Don't buy the cheap knock off stuff!
Those BBD Chinese carbs cost $357 in New Zealand, and that's what will keep me using rebuild kits on my old Carters when necessary. And also why Iv'e expressed an interest in seeing an instructional video on re bushing throttle shafts.
@@DeltatechActual Sorry to hear about that . I've got one old BBD that my father had rebushed way back in about 1987 .It was a success and is still good.
I rebuilt a Chinese knock off of the Carter YF 1bbl carb, with hot air choke. The only problem with the carburetor was that was they didn't drill the vacuum passage for the hot air choke. An electric choke solved the problem.
Strombergs❤❤3 2setup on a 283 in a 55 Chevy, the middle carb was a Rochester but the two end carbs where Stromberg 97,she wasnt bad for getting groceries
Years ago I worked on a Johnson snowmobile with a Wankel rotary engine in it. The carburetor had somehow broken up and most of the carburetor body was sucked through the engine and wound up in the muffler. With a couple days of work I lapped out the scoring on one end plate. The rotor, housing, and the other end plate all had to be replaced (as did the carburetor ;).
One problem I've seen with the Chinese copy carbs is the quality of the zinc alloy can be very poor. One of mine has developed "zinc sickness" where lead contamination of the metal starts it crumbling especially round bosses and screw holes. Doesn't help that I live in a cold and wet climate.
I had a bolt tap about that size go down the intake & into the engine. Valve & piston damage. A complete tear down was necessary & rebuild. You got lucky Tony.
I bought a CHINA AUTOLITE 2100 from that guy on EBAY. He advertised he'll set it all up for your engine. It wasn't even close ....I had to re-jet it twice to get it right
I'll have to have a look at them. I have 3 of those carbs still sitting in their boxes. Thanks for the heads up. If that's not a great interference, maybe use a drop of Loctite bearing retainer?
@chrisfreemesser5707 Had a look over my 3. 2 of them bought recently, and a bit worrying. The third one, bought about 2 years ago, must have been assembled by a stronger 9yo girl. More detail in my short, reply to UTG on the TAVO place. It won't let me post the magic word.
Love the content man! Great info. I work Aviation, light GA stuff and have for years. When installing parts, an inspection of the part to be installed is required. A form and function inspection. Catching stuff like that in our parts is unheard of, but a good inspection would catch that kind of thing. A good look and a tug, pull, turn or other wise manipulate. Check the parts.
That piece absolutely could have killed that engine, i lost a Pontiac 455 once to one of the little screws on the bottom of a quadrajet falling out, broke a piston and put a long crack in the cylinder wall.
I bought a distributor for a Toyota one time. After checking it out I discovered it was indexed 180 degrees off. If I would have used it the car never would have started.
Original carbs are usually plated inside out to prevent corrosion in the bowl due to ethanol in the gas. I have never seen a plated knockoff China carb.
keep an eye out for leaks from the bushings of the throttle shaft. Mine leaked after about 3 weeks. My be because of Ethanol eating the bushings, I don't know.
@@DeltatechActual you could be right about running the ethanol 🤔 I'm not that advanced, I'm just a guy burning 91 octane. 😂 I do completely disassemble the carbs before running them but I would do that with original webers as well
@@DeltatechActual Yeah, they about need the words Lawnmower gas on the ethanol free pumps, to warn homeowners they need that gas. Heck you'll never get a year from the fuel lines, in general weed eaters or chainsaws on the market now. I removed a fuel shut off that was full of rubber gunk, from the black fuel line on a lawnmower. 2017 model.
After seeing a guy on you tube speak well of a cheap Sportster carb he used, I ordered one instead of a rebuild kit. The carb worked, but everything about it looked and felt so cheap, right down to the jets. I had to take it off and go with the original carb.
I bought an Edelbrock 1405 copy from China, the original seals lasted about 3 weeks. Leaks from the throttle linkage shaft that goes through the whole bottom housing. The step up pistons had to be reworked to slide and keepers were installed wrong, other than that it works ok. Buy a good rebuild kit with all new seals if you go this route.
Hey Tony! Love your show! Uncle Kathy produces some fine entertainment! I just wanted to remind you if you are going tho keep the Chinajet (and I wouldn't), too make sure there throttle shaft screws are staked. $1 says they aren't.
The first department to get cut when I worked in it was the qc department. If they slowed down and had to they’d let a person or two go. Quality didn’t suffer but that’s in the USA in china 🇨🇳 they just follow a process and it gets shipped. That’s what my supervisor who traveled to china for our company told me if they have a qc department it’s only for visitors otherwise they’re assemblers
Had oil leak come back on a Toyota. Just got brand new filter cap from orielies. Lube tech did it so I was tasked to double check. The brand new o-ring was covered in splits-cracks. Like it was counterfeit part.
Yeah I’ve run into issues with Chinese carbs- have tried to use on a tractor, an old Jeep CJ and even a lawn tractor and like you said- they generally will work, or can be made to work but not without issues- leaky gaskets from the get go, holes misaligned, throttle plates bending too easy etc. By the time the issues were fixed I could have bought either a rebuilt or ( if available ) a new US made one not even factoring in my labor. I’ll still go with rebuilding the old when I can still get (quality) kits . That being said I’d bet they could make quality parts if it was specked properly , they were made at a certain price point based on what the procuring company said they would pay for them. Same thing applied back when things were first being outsourced to Japan or Taiwan. US company says build me this part for X and I’ll order 10,000. Like the man says- you get what ya pay for - and up to me buy US whenever possible
We had almost the same thing happen with our 1971 VW Beetle some time around 2007-2008. I had forgot to press the brass acellerator pump nozzle properly into it's hole. It fell out and got sucked into the engine. This was on a genuine old Solex carburetor, and the error was all my fault. It won a brief fight against the spark plug on cylinder one before it got blown out and ended up in the muffler. With a new spark plug the engine ran just as good as before so I did not bother any more with it. Last year when I opened up the engine for the first time since 2006 I was curious to see if there was any signs of the old incident. But there was none. Not a single mark on either the piston, cylinder or head. They made these things out of brass for a good reason.
I envy younger people these days, they don't go through life angry like I am. They're used to Chinese parts failing, where I remember going to a parts store not having to ask where something is made every single time, or replacing something once and it lasted. Today, it's always a crap shoot, some companies try to mislead us as to where a part is made.
I’ve found several on customers’ cars, that either don’t transition between circuits well, or idle erratically. I’ve tried all the tricks, jets, adjustments, etc.. I’d say that about 50% (conservatively) just don’t run right, and really can’t be made to. *Edit.. sloppy throttle shaft clearances have been an issue more than once.
Hell yea, glad you got that piece outa there easily. I woulda lost sleep over that falling in my engine if it went all the way in😄. Brass or not that just can’t be good for the valves, rings, cylinder.
Firestone shop broke off three wheel studs and when I replaced them the Chinese OEM studs of course were different. I've heard many stories about new parts that don't work. No more Chinese mini bikes either. They fell apart every time used. I think they can defeat Loctite.
Was that little girl actually working in the Wing Dong province ? 😂 Nice 👌 Her grandfather was an exchange student in the states back in '80s named Long Duck Dong
Not surprised, weve had about 3 standby generators no good right out of the crate in about as many months and it's a name brand that's been around for over 100yrs.
Back in the 70's my aunt's friend came to to work on her Valiant that wouldn't start. Even back then he's complaining Chrysler junk, piece of Carter junk made in Taiwan and I think it actually was. The problem ended up being the leather accelerator pump was folded over somehow...
ive seen a 10mm nut totally destroy an engine when it went into the intake.. (actually i think it was smaller than 10mm) was a V6 90s hilux surf.. it came off a loose MAF sensor to airbox mount.. went up the intake and into the motor.. broke a valve off, smashed a piston, destroyed the engine
I've used a few Chinese marvel schiebler carbs for old farm tractors. I've learned the bowl gaskets for a marvel will not match up to the china version. And some weight like 7lbs and some feel like a feather. Different alloys at the time I guess
I remember when Tony replaced a marine carb with a knock off. It worked great. He commented on how much lighter the knock off was compared to the original. I wonder what the knock offs are made from
I recently bought a Weber 38/38 from Pegasus Auto for nearly $500. Its got a stumble like the carb is too big under full throttle. I've jetted it and adjusted things correctly. They weren't much help. I'm going to have to dive into accelerator pumps and whatnot. The old Weber ran better. Even genuine carbs aren't put together very well anymore.
Mr. Uncle Tony Garage, we, in Chyna, are very concerned. We Will fly you and the carb to our factory in Cyna in Ringdon. Please to us send your information so we may fly you to us. 🤭🤭
Lucky, lucky, lucky. Timing is everything. Having said that, your Cuda needs a timing chain. Bad response on throttle ? Loctite that tube and plate screws.
There's a man not far from me who sells reconditioned workshop equipment, lathes, mills, that sort of thing. A lot of it is too big for hobbyist' so he imported a container load of Chinese lathes, really dirt cheap when buying that quantity. Every one had to be stripped and sand blown out of the castings, all the gib strips had to be replaced as the supplied ones were mild steel, some of the beds were so distorted they had to be scrapped, barrel markings were glued on and not engraved ...... and much, much more. As so many parts were sub-standard he ended up with just over half the shipment being useable, some spare parts and a load of scrap .......... buy cheap, get junk (and not the floating kind).
Many years ago a friend of my brother came over to have him look at his truck because it had a loud knocking sound. The knock was hard to figure out at first but my brother figured out a head had to get pulled. He pulled the head and found a "little tiny screw" imbedded into the top of a piston. Where did that tiny screw come from? It was from one of the butterflies on the throttle shaft.
Heard a click while removing glow plug on 5.7 olds diesel,half fell in.Didn’t want to pull head,access pre combustion chamber to remove. “It will blow out the exhaust” …… It didn’t. After some miles all the new noises stopped,but the oil level kept rising. Engine ran like crap.Diesel mechanic friend concluded pc. got hammered into top of piston till it burned thu.Was dumping fuel into crankcase.😵💫
Im in the middle of building a 1985 suburban, dually conversion with a sm465 and a 454, next on my list is my 66 charger that i have a motorhome 440 for
What luck, a little daub of 3 m weather strip asheisive will hold it in place . Its job is air vent for atmospeheric pressure into the fuel bowl. When I went to Bfriggs and Stratton school they taught me how carberators don't work off of vacum, the neck down in the carb (venturi) causes a low pressure area and by the atmospheric pressure from bowl vent gasoline is pushed to that low pressure area. Some carbs have hose going from side of top of the carb to the fender to some plastic box, plugging that hose with a bolt causes all kinds of problems, all carberators have a bowl vent for atmospheric pressure to get in the bowl area. Its more then just an air vent!
Ive been watching your channel for a while now and learned alot from it especially about carburetors. I was wondering Do you have any tips for classic cars and carbureted engines in extreme cold other than block and oil pan heaters. I daily my classics year round and this past winter i left my LTD running for 3 days straight becuase it was minus 50 and even with those i was scared it wouldnt start if i shut it off
It's easy to blame China, but the real problem is that the buyer wants the lowest price possible and China is willing to take steps that American companies wouldn't, like hiring near slave labor, working them insane hours and shipping everything that comes off the line with little or no final inspection. And we, the American consumer, did that by abandoning products made in the US because they cost too much. And this isn't new, it's been going on for decades. Hell, we wouldn't pay for a $100 bicycle made by Schwinn in the USA and after years of holding out, they finally had no choice but sell out to China. WE did that. We're to blame.
It's not so much what the consumer was willing to pay than it is what giant retailers like WalMart forced manufacturers to do. They'd make a manufacturer totally dependent on selling at WalMart, then kept demanding the products at lower and lower prices until the company HAD to choose between moving production overseas to meet WalMart's pricing demands or going out of business
Exactly. And the only reason Walmart gets by with the garbage it sells is because we, the consumers, buy it. Stop buying junk and Walmart and others will get the message and carry decent stuff.
Agreed. In the era people fondly remember of high quality household products (like vacuums, kitchen appliances, etc.), they don’t remember or realise how expensive they originally were. The Sunbeam toaster I use daily today originally retailed in 1954 for the modern equivalent of $300 or $400, and vacuums weren’t a frivolous, stupid gift but a major expense for the home. The upside was that those things lasted. What we build now on the cheap does not.
Somewhere in a book I read THE CHINESE ARE COMING - all that's holding them back is their quality. My observation has been, as far as quality goes, that the Chinese are about where Japan was back in the 70's and 80's in terms of the quality of the products. But, quality is something that can be learned.
Unfortunately this kind of thing is only becoming more common I just replaced a transmission mount on a power glide a month ago because the old one was Bluetooth The new one became Bluetooth in a week
with the overseas carburetors i rebuild them even when they are new before installing them...there's always rough edges and left over flashing etc inside them...
in about 1987 i was a professional transmission rebuilder, i did that for 45 years, retired now. one day in 87 my younger brother had a 1968 Pontiac executive 2drht, i had never seen one, it was black and beautiful! he came to my shop and asked me, hey you know that wing nut that is on the breather? i said yea, he said what would happen if you dropped it down the carb. with the motor running? i said you didn't do that did you? he said he ran out of gas and was pouring gas into the carb. and it fell in! the engine was making a knocking noise on the driver side. i pulled the head and there the nut was as flat as a sheet of paper on no.1 piston! it didn't hurt the engine at all he passed away unexpectedly of a heart attack 2 months ago at 57 years old. he still had the nut in a jar. Billy you are missed little brother,,,,,,,,,,,,,,,,,,,,,
Sorry for your loss. God bless you and your family, thanks for sharing, stay strong brother.
Condolences, you were very fortunate to have a brother you could make memories with.
Sorry to hear that, our condolences!😢
Had that happen with a vw beetle I had.
It was banging so hard but it was my daily I said eff it and drove.
All the sudden the noise stopped.
Later disassembled and it had 13mm nut indentions on the piston.
And when the noise stopped it shot into the muffler.
Still ran great tho!
Little 1600 vw motor ATE a full on 13mm m8x1.25 nut
AmaZing.
So a Chrysler should be able to eat a 5/8 nut
Maybe even a 3/4!!!
Here's to Billy, trying to play the question off like it didn't just happen lol

You start the engine with the plug not in, and the debris gets blowed out the spark plug hole - kind of like with those crappy two-piece plugs used in Ford 4.6 3Vs. Plug breaks off in the cylinder, you drill through the remnants and thread in a stud for a puller. You also end up with some ceramic in your cylinder, and best practice at this point is what I stated above. With video, you can see the ceramic bits fly out of the cylinder!
Speedy dry does interesting things when poured down the intake of a lawnmower engine, while the throttle is tied wide open.
Yup, after 2 handfuls slowly poured down the intake, I removed the plug and it looked brand new.
As if it just came out of a sandblast cabinet or something. 😂😂

It was some 4cyl pos, and since I was the newer guy the boss knew he was going to lose his butt, but he might as well save what he could.
All 4 plugs snapped off , so we figured the best was to hammer the porcelain in.
The threaded part turned in the hole no problem,but the carbon lip wouldn't let them come out.
I threaded em in so they fell in the cylinder ,and proceeded to take a punch or 3 of different sizes and bust that thing into pieces on top of the piston.
Took about 3 hours between hammering and using magnets and whatnot but it was successful.

I remember a while ago my son bought a little "pit bike" very popular these days, first thing he did was to make sure all the bolts were tight. Surprisingly enough they weren't. He forgot about the chain guide, low and behold it fell off after the first ride. This kind of reminds me of the old saying, " The bitterness of poor quality, lingers longer then the sweetness of a cheap price".
I got a Chinese pit bike, those dumbasses put the carb on the bottom of the engine with no guard, so if you high center the bike the carb is eating shit.
Sadly it was probably assembled by an American.
G'day from Oz, I recently bought an oil pump for our Holden v8, looked upon as a quality brand for as long as I can remember. I disassembled it to check it and cleanup the casting oil passages, I found machine shavings right through it and the end tolerances of the gears way to great. That would have destroyed a brand new engine, so to anyone check and recheck, it might take a bit longer, but it's worth it.
Thanks Tony and your wife for your efforts, I am keeping an eye on you all.😉
After THREE different crankshaft position sensors from China left me stranded, I bought a NGK brand that says Made in USA. Now my 30 year old Dodge starts and runs reliably.
I went through three heater control valves in a ford ranger in less than a year before I decided to go with the Motorcraft. It would have been cheaper and much less labor and aggravation to have done that in the first place.
Something about "Chinesium". It doesn't seem to hold up well with liquids, like gasoline, motor oil, engine coolant, water, you name it. If it lasts 6 months, you feel like you got a winner, until you find yourself at the parts counter a few days later.
I have both a crank and cam sensor doa from them in box, returning them both!
Carter/Edelbrock -- I swear by them
Chinese knockoffs -- I swear at them
I work on the production floor for one of the Big Three and have been with the company for 20ish years. We are seeing all kinds of problems with everything that comes from overseas, I've never seen anything like it. We are seeing 50% to 90% supplier defects, the supplier reps are saying that they are having to rework everything, especially the stuff coming from the Big Red Flag country. Rumor is that Detroit is telling suppliers to start bringing stuff back to the US. It's going to get crazy, and much worse before it gets better.
"You get what you pay for" applies here. I work in maintenance for a company that builds the electrical harness for GM, Ford and Mercedes. Different customers and different QC.
Chinese tit for tat
USA specs the parts. Its American companies ripping you off. If they payed and specified for higher quality, you'd get it, but they won't make as much profit off you. Let's be honest. Blame the companies asking for low grade big profit parts 👌
Opening up and finding an unassembled or partially assembled box of parts is one of the reasons that you see "Assembled in the USA" on some items.
@@leviswranglers2813 I believe it! That’s one of the contributing factors to me getting burned out of the automotive industry and quitting last year. Ran a shop for 14 years. I’d had enough!
I am such an advocate for rebuilding sure stuff gets worn out but you can fix it, people have no idea the gold they throw away that carb, distributor or whatever it may be is so much superior in terms of materials alone
Yessir, happens to me all the time. I'm a vintage motorcycle restoration and repair service and I hear it all the time. Oh, I can get a complete new carb on amazon or ebay for 120 bucks! I proceed to tell them the factory original carb is worth between 400-900 bucks depending on the carb and the "quality" of the cheap carb will never come close, never mind performing anywhere near the oem parts. 😂❤
Bought a knock off china Autolite 2100 from Amazon a year ago for my 72 F250. Cost $84. Absolutely zero complaints. It worked so well I bought another one to keep tucked away.
Hey, sometimes you luck out with them. If you find a good Chinese distributor, hold them best you can.
You might want to test the spare NOW.
The brass fuel inlet fitting on old Solex carbs for air cooled VW's is notorious for loosening after years of service. Especially when folks install a plastic filter inline between the carb and fuel pump. Heat cycles and vibration cause the inlet tube to fall out, while the car keeps running and the fuel pump keeps pumping fuel all over the engine compartment. Lots of VW's have gone down in flames this way.
I pull that inlet, scuff it with coarse sandpaper, and JB weld it back into place. Never had an issue with it in 30 years of driving these old beaters.
well trained 9 year old made me spit my drink
Chinese 9yo factory worker has more work motivation than any American child in middle school
Yeah, me too.
I knew I saw something fall into the carb in the last video! 😮
An old short track racing superstition involves keeping peanuts out of the pits. The origins come from the small arenas used for midget racing where the pits were located beneath the grandstands. People eating peanuts would drop the shells which in turn found their way into the downdraft carburetors. How often this occurred is impossible to know but it happened enough that it became a long lasting superstition.
Side note: I had an air cleaner tie down bolt break loose and fall into my engine. Destroyed the engine. Found the mangled up pice atop one of the pistons. I keep the bent piece on my key ring ever since to dispel anyone claiming it's an old mechanic tale.
Someone sends a Chinese company an original carb and asks it be reproduced for $1. That is the problem, pay more and get better quality but they’d rather have maximum profit
I've purchased quite a few Chinese knock off carbs for motorcycle, the first thing I do is take them apart , and inspect them and rebuild , I've seen where the casting needed to be filed so main jets fitted correctly.
Hey, it's not just the Chinese parts...
I had a 1970-something Ford van we had converted to a camper. It had the 300 CI inline 6-cylinder in it. We had traveled all around the Western US and Canada with it.
One trip from San Francisco Bay Area to Seattle, 2nd day out we're on the lonely stretch of I5 just over the Oregon border, there is suddenly a loud knocking in the engine. Oh crap! Luckily we have cell service and are able to call for a tow service.
Our luck is still with us, the tow driver says we are just 5 or 6miles from Port Orford, Oregon where there is a Ford truck service shop!
He's right! And, even better, it is a 60- or 70-year old shop, the type with all the machinery run off big belts in the ceiling. They specialize in heavy duty logging trucks, but were happy to help us with our camper van. Even let me do some of the work myself.
Long story short, we pulled the head and found one of the little screws that held the bracket for the air cleaner had come loose and got sucked into cylinder #1. Minor scrapes on the top of the piston, but no real damage.
We had to wait several days for a head gasket to be delivered, during which we had a really enjoyable time in the little town of Port Orford (five star restaurant, great accomodations, neat local history, unique tourist shops, winderful people). We had planned to just drive through, but thanks to the breakdown, we may have had the best 3 days of vacation in that quaint little town.
Finally got the parts, learned that you could use metallic spray paint to seal a head gasket, paid a total of $260 parts and labor, and were on our way.
Oh, and we put another 75,000 miles on that engine, which already had 150,000... and it was still running strong when we gave the van to our son-in-law for his painting business.
. . . so the upshot of your story is after several cross-country road trips, a screw (that hadn't been touched from the factory, I guess?) rattle loose & finally came off.
That means its' actually a Chinese knockoff thing.
I bought a Chinese carburetor for a 1985 Suzuki FA50 moped that I snagged for free for the wifey many years back. No matter what I tried with the main jet I just couldn’t get it to stop 4-stroking - it was pig rich. Ended up having to drill out one of the air bleeds for the main circuit. Thing ran mint after that.
Also bought a pair of 900W 2-stroke generators from Harbor “Fright”. Right out of the box, the carburetor was clogged with metal protectant. Then parts of the exhaust fell apart. Ended up having to go through the whole thing and tighten up every single nut and bolt. I can only imagine what the piston & rings look like. I didn’t dare look…😂
You realize that your Suzuki came from there in the first place right? A carb from there would be closer to oem than a knockoff.
@@Beverlys-Hillbilly What?? It came from JAPAN, not CHINA! HUUUUUGE difference in quality between the two.
@@SmittySmithsonite Especially if the Japanese are doing QC.
Thank G-- I found a NOS '73 BBD for my '72 318 Satellite on Ebay, On another note, rebuilt a carb on a 1985 Dodge Caravan 2.5 liter. Could only find three carb retaining nuts when re-installing the carb. Looked everywhere. Next day taking a test drive it was running like new, then lost power. The carb nut had fallen into a cylinder and it began to run on three cylinders instead of four after that. Needed to remove the head for a valve job. Combustion chamber was all scarred up but it survived to run another day.
Loved those old 2.2/2.5s!!
Lost the head gasket on one in our minivan the saturday night we were moving.out of state. Short of time, I thrashed. Left the manifolds on and was able to do the job in about an hour...
Van ran peachy for years after that. Sold it to a coworker who drove it many years further. Kinda miss it, five speed minivans are fun!!!😂😂
Things like this (and the fuel pump issue you had) are what makes me so nervous, especially on big jobs like the engine I built for my truck. And most recently the A518 transmission I just rebuilt for it.
This is my first automatic transmission rebuild, so I am already nervous about my skills let alone the quality of the new parts. (Especially seals, servos, and electronics).
I actually put it together and took it apart 3 times before I finally installed it. Just to double, triple check my work.
I had alot of great help from the online community, many of whom are subscribers here.
To all those that helped me, Thank you so very much.
There is no "quality control" in manufacturing processes for a carb like that. They follow a process and thats it.
they have no quality control period!
Damn, I have that same carburetor on my 1966 Charger! Thank you I'm going out right now and checking!!
I was a Hyundai/kia technician back in the early 00's I had a kia sedona minivan come in with less than 10k miles on it. It had a top end knock. Being they had a 10 yr, 100k warranty they said replace the engine whole. New engine came with equipped intake to pan. I swapped it out and sent it on its way. Kia wanted the engine obviously but I wanted to know why it knocked. I tore it down to find #2 cylinder had a tiny screw embedded into the piston. Further inspection lead to it was one of the many intake runner throttle blade screws. I had to make a report to the tech center. A week later kia came out with a TSB for the throttle blade screws. Ugh! That sucked. Thanks for sharing.
6:57 UT you must have a small block four barrel intake laying around the shop. Throw that thing in the garbage and put a 500 or 600 cfm edelbrock on it .
My thoughts too a single barrel on a V8 is just so wrong
I bought a pirate copy of ‘101 Dalmatians’, and there were only 92. *_/shakes fist wildly/_*
From my understanding, China can produce fine products if the American companies that are having them made insist on QC and supervise it themselves. If they just order the parts and accept what they get, the manufacturers will skimp on QC and save the dime.
China cant even produce a proper fuel Hose.
.
Stop making in china all together
this is true and a part of the big picture people should be aware of
Or if those American companies don't just buy the cheapest going for max profit
Hello Uncle Tony and Uncle Kathy 👋
Buffalo!
@@chrisfreemesser5707 Chris Roc 👋
I've got a '51 Farmall Cub tractor that I use around our place much like normal folks do an ATV. The body castings for the original carb were warped to the point they wouldn't seal with the gaskets. New carbs are unobtanium and used ones are an expensive gamble when you can find one. The Chinese knock offs are cheap enough but with a very bad reputation. I bought one with the idea of taking it apart and putting it back together with as many of the original parts as I could get to fit. The only original part that didn't fit was the brass fuel inlet fitting which had different threads. I managed to get a new fuel hose adapter that fit the new inlet and that thing runs like it came from the IH plant which has been closed for years.
2:35 Murphys law though, the more expensive the engine is ,the more likely it is to suffer damage from a gnat flatuating nearby.
Yep.
With the cost of rebuild kits having gone into the stratosphere, these start looking much more attractive than a year ago. Thankfully Amazon returns are pretty painless usually to risk a China Carbonator.
Yes, when a simple 2bbl carb rebuild kit runs $70+ ! Stockpile used carbs that look serviceable. Just make notes on what they came from, junk today/gold tomorrow. Don't buy the cheap knock off stuff!
Those BBD Chinese carbs cost $357 in New Zealand, and that's what will keep me using rebuild kits on my old Carters when necessary. And also why Iv'e expressed an interest in seeing an instructional video on re bushing throttle shafts.
MIne leaked from those bushings after 3 weeks. $180 in America.
@@DeltatechActual Sorry to hear about that . I've got one old BBD that my father had rebushed way back in about 1987 .It was a success and is still good.
I've used thin o-rings to seal up the shafts on old worn out throttle plates. Usually on Q-Jets
Got mine for $123AU across the ditch. West Island 😆
@@TAVOAu In the land of milk and honey. 🙂
I rebuilt a Chinese knock off of the Carter YF 1bbl carb, with hot air choke. The only problem with the carburetor was that was they didn't drill the vacuum passage for the hot air choke. An electric choke solved the problem.
It's a classic situation of a part that costs pennies leaving you at the side of the road!!!!
Strombergs❤❤3 2setup on a 283 in a 55 Chevy, the middle carb was a Rochester but the two end carbs where Stromberg 97,she wasnt bad for getting groceries
That kid who installed that is now getting a whooping. Have a good day.
Nah, they don't care once it leaves the door. The end consumer can't tell what factory this stuff comes from.
A bad reality with no improvement in sight for the near future. I'm just glad you call it a carburetor and not a "fuel make it happener"
Years ago I worked on a Johnson snowmobile with a Wankel rotary engine in it. The carburetor had somehow broken up and most of the carburetor body was sucked through the engine and wound up in the muffler. With a couple days of work I lapped out the scoring on one end plate. The rotor, housing, and the other end plate all had to be replaced (as did the carburetor ;).
“By the well trained 9 year old girl” 🤣. Thanks Tony for what you do!
One problem I've seen with the Chinese copy carbs is the quality of the zinc alloy can be very poor. One of mine has developed "zinc sickness" where lead contamination of the metal starts it crumbling especially round bosses and screw holes. Doesn't help that I live in a cold and wet climate.
Uncle Kathy we see your work in every video, and we all thank you very much!
The only safe way to use one of these is to put an air filter AFTER it.
I had a bolt tap about that size go down the intake & into the engine. Valve & piston damage. A complete tear down was necessary & rebuild. You got lucky Tony.
I found a 1955 quarter in the oil pan of a 60s Buick that had never been apart. Always wondered.
Hey Lobo that would be weirder if the numbers were other way round
@@johngibson3837 lol it sure would!
Cool , thanks , I have to check mine.
I bought a CHINA AUTOLITE 2100 from that guy on EBAY. He advertised he'll set it all up for your engine. It wasn't even close ....I had to re-jet it twice to get it right
Lots of those vent tubes are steel, definitively not always soft brass. A steel vent tube could do some serious damage.
And if not that, the dozens of other screws, caps, jets, etc that ARE made of steel.
"Could" 😂😂😂
Yeah we get it. Calm down.
I'll have to have a look at them. I have 3 of those carbs still sitting in their boxes. Thanks for the heads up. If that's not a great interference, maybe use a drop of Loctite bearing retainer?
Let us know if you find anything amiss Tavo...Tony's issue could have been a one-off mistake or a fault common to every single carb they made
@chrisfreemesser5707 Had a look over my 3. 2 of them bought recently, and a bit worrying. The third one, bought about 2 years ago, must have been assembled by a stronger 9yo girl. More detail in my short, reply to UTG on the TAVO place. It won't let me post the magic word.
You might want to check the screws in the butterfly's.. they will come lose and fall out too.
Love the content man! Great info. I work Aviation, light GA stuff and have for years. When installing parts, an inspection of the part to be installed is required.
A form and function inspection. Catching stuff like that in our parts is unheard of, but a good inspection would catch that kind of thing. A good look and a tug, pull,
turn or other wise manipulate. Check the parts.
That piece absolutely could have killed that engine, i lost a Pontiac 455 once to one of the little screws on the bottom of a quadrajet falling out, broke a piston and put a long crack in the cylinder wall.
I bought a distributor for a Toyota one time. After checking it out I discovered it was indexed 180 degrees off. If I would have used it the car never would have started.
Original carbs are usually plated inside out to prevent corrosion in the bowl due to ethanol in the gas. I have never seen a plated knockoff China carb.
Are we talking about small engine carbs? Ethanol gas came on the market after the automotive manufacturers had pretty much stopped using carbs.
I saw some guy say "your vent tube fell into the float bowl".
I've recently started using the Chinese weber knock offs of the 44 and 40 IDFs, so far so good 🤞
keep an eye out for leaks from the bushings of the throttle shaft. Mine leaked after about 3 weeks. My be because of Ethanol eating the bushings, I don't know.
@@DeltatechActual you could be right about running the ethanol 🤔 I'm not that advanced, I'm just a guy burning 91 octane. 😂 I do completely disassemble the carbs before running them but I would do that with original webers as well
@@DeltatechActual Yeah, they about need the words Lawnmower gas on the ethanol free pumps, to warn homeowners they need that gas. Heck you'll never get a year from the fuel lines, in general weed eaters or chainsaws on the market now.

Hi Tony, a drop of Red LocTite would be an extra security step, Keep the videos coming .

Good recap, super lucky save! I’m glad it didn’t make it past carb. Good deal
Uncle Tony for president!
After seeing a guy on you tube speak well of a cheap Sportster carb he used, I ordered one instead of a rebuild kit. The carb worked, but everything about it looked and felt so cheap, right down to the jets. I had to take it off and go with the original carb.
I bought an Edelbrock 1405 copy from China, the original seals lasted about 3 weeks. Leaks from the throttle linkage shaft that goes through the whole bottom housing. The step up pistons had to be reworked to slide and keepers were installed wrong, other than that it works ok. Buy a good rebuild kit with all new seals if you go this route.
It was meant to be a temp replacement for the Edelbrock that needed rebuilt while rebuilding it and didn't even serve that purpose.
Tony, Bottle Rocket needs some love. She needs a few passes down the track to keep the fluids moving and the seals wet.
Ya we watch your videos for the great lighting 😂
Hey Tony! Love your show! Uncle Kathy produces some fine entertainment! I just wanted to remind you if you are going tho keep the Chinajet (and I wouldn't), too make sure there throttle shaft screws are staked. $1 says they aren't.
UT said that right in the video, he recommended checking that the throttle plate screws are staked.
The first department to get cut when I worked in it was the qc department. If they slowed down and had to they’d let a person or two go. Quality didn’t suffer but that’s in the USA in china 🇨🇳 they just follow a process and it gets shipped. That’s what my supervisor who traveled to china for our company told me if they have a qc department it’s only for visitors otherwise they’re assemblers
Had oil leak come back on a Toyota.
Just got brand new filter cap from orielies.
Lube tech did it so I was tasked to double check.
The brand new o-ring was covered in splits-cracks.
Like it was counterfeit part.
Yeah I’ve run into issues with Chinese carbs- have tried to use on a tractor, an old Jeep CJ and even a lawn tractor and like you said- they generally will work, or can be made to work but not without issues- leaky gaskets from the get go, holes misaligned, throttle plates bending too easy etc. By the time the issues were fixed I could have bought either a rebuilt or ( if available ) a new US made one not even factoring in my labor. I’ll still go with rebuilding the old when I can still get (quality) kits . That being said I’d bet they could make quality parts if it was specked properly , they were made at a certain price point based on what the procuring company said they would pay for them. Same thing applied back when things were first being outsourced to Japan or Taiwan. US company says build me this part for X and I’ll order 10,000. Like the man says- you get what ya pay for - and up to me buy US whenever possible
agree, throttle shaft bushings leaked after 3 weeks. I wonder if it's because of Ethanol?
We had almost the same thing happen with our 1971 VW Beetle some time around 2007-2008. I had forgot to press the brass acellerator pump nozzle properly into it's hole. It fell out and got sucked into the engine. This was on a genuine old Solex carburetor, and the error was all my fault. It won a brief fight against the spark plug on cylinder one before it got blown out and ended up in the muffler. With a new spark plug the engine ran just as good as before so I did not bother any more with it. Last year when I opened up the engine for the first time since 2006 I was curious to see if there was any signs of the old incident. But there was none. Not a single mark on either the piston, cylinder or head. They made these things out of brass for a good reason.
You should have a double return spring on that carb. Would not pass an NHRA inspection without it.
I envy younger people these days, they don't go through life angry like I am. They're used to Chinese parts failing, where I remember going to a parts store not having to ask where something is made every single time, or replacing something once and it lasted. Today, it's always a crap shoot, some companies try to mislead us as to where a part is made.
I’ve found several on customers’ cars, that either don’t transition between circuits well, or idle erratically. I’ve tried all the tricks, jets, adjustments, etc.. I’d say that about 50% (conservatively) just don’t run right, and really can’t be made to. *Edit.. sloppy throttle shaft clearances have been an issue more than once.
Hell yea, glad you got that piece outa there easily. I woulda lost sleep over that falling in my engine if it went all the way in😄. Brass or not that just can’t be good for the valves, rings, cylinder.
How is it different really when you have to check everything? We should be well past that point
AWESOME info...the Q&A in some things have gone to the dogs....MOPAR 4 EVR.
Firestone shop broke off three wheel studs and when I replaced them the Chinese OEM studs of course were different. I've heard many stories about new parts that don't work. No more Chinese mini bikes either. They fell apart every time used. I think they can defeat Loctite.
Was that little girl actually working in the Wing Dong province ? 😂 Nice 👌 Her grandfather was an exchange student in the states back in '80s named Long Duck Dong
A Chinese part I owned made in Dong had a dent in it. It was a Ding Dong.
Not surprised, weve had about 3 standby generators no good right out of the crate in about as many months and it's a name brand that's been around for over 100yrs.
Back in the 70's my aunt's friend came to to work on her Valiant that wouldn't start. Even back then he's complaining Chrysler junk, piece of Carter junk made in Taiwan and I think it actually was.
The problem ended up being the leather accelerator pump was folded over somehow...
ive seen a 10mm nut totally destroy an engine when it went into the intake.. (actually i think it was smaller than 10mm) was a V6 90s hilux surf..
it came off a loose MAF sensor to airbox mount.. went up the intake and into the motor.. broke a valve off, smashed a piston, destroyed the engine
I've used a few Chinese marvel schiebler carbs for old farm tractors. I've learned the bowl gaskets for a marvel will not match up to the china version. And some weight like 7lbs and some feel like a feather. Different alloys at the time I guess
I remember when Tony replaced a marine carb with a knock off. It worked great. He commented on how much lighter the knock off was compared to the original. I wonder what the knock offs are made from
Just aluminium
I recently bought a Weber 38/38 from Pegasus Auto for nearly $500. Its got a stumble like the carb is too big under full throttle. I've jetted it and adjusted things correctly. They weren't much help. I'm going to have to dive into accelerator pumps and whatnot. The old Weber ran better. Even genuine carbs aren't put together very well anymore.
Mr. Uncle Tony Garage, we, in Chyna, are very concerned. We Will fly you and the carb to our factory in Cyna in Ringdon. Please to us send your information so we may fly you to us.
🤭🤭
Good advice!

Spark plug wire quality is absolutely terrible lately. Brand new ones tear apart when removing from spark plug. Didn't have that problem 20 years ago.
Lucky, lucky, lucky. Timing is everything. Having said that, your Cuda needs a timing chain. Bad response on throttle ? Loctite that tube and plate screws.
There's a man not far from me who sells reconditioned workshop equipment, lathes, mills, that sort of thing. A lot of it is too big for hobbyist' so he imported a container load of Chinese lathes, really dirt cheap when buying that quantity. Every one had to be stripped and sand blown out of the castings, all the gib strips had to be replaced as the supplied ones were mild steel, some of the beds were so distorted they had to be scrapped, barrel markings were glued on and not engraved ...... and much, much more. As so many parts were sub-standard he ended up with just over half the shipment being useable, some spare parts and a load of scrap .......... buy cheap, get junk (and not the floating kind).
buy American or rebuild when possible
Many years ago a friend of my brother came over to have him look at his truck because it had a loud knocking sound. The knock was hard to figure out at first but my brother figured out a head had to get pulled. He pulled the head and found a "little tiny screw" imbedded into the top of a piston. Where did that tiny screw come from? It was from one of the butterflies on the throttle shaft.
Heard a click while removing glow plug on 5.7 olds diesel,half fell in.Didn’t want to pull head,access pre combustion chamber to remove. “It will blow out the exhaust” …… It didn’t. After some miles all the new noises stopped,but the oil level kept rising. Engine ran like crap.Diesel mechanic friend concluded pc. got hammered into top of piston till it burned thu.Was dumping fuel into crankcase.😵💫

That could have been catastrophic. 😳😲😮
You need to replace the throttle return and back up safety spring.😁
What luck, a little daub of 3 m weather strip asheisive will hold it in place . Its job is air vent for atmospeheric pressure into the fuel bowl. When I went to Bfriggs and Stratton school they taught me how carberators don't work off of vacum, the neck down in the carb (venturi) causes a low pressure area and by the atmospheric pressure from bowl vent gasoline is pushed to that low pressure area. Some carbs have hose going from side of top of the carb to the fender to some plastic box, plugging that hose with a bolt causes all kinds of problems, all carberators have a bowl vent for atmospheric pressure to get in the bowl area. Its more then just an air vent!
Good save.Good eye.
Throttle blade screws are next old man.
The future is now.
Ive been watching your channel for a while now and learned alot from it especially about carburetors. I was wondering Do you have any tips for classic cars and carbureted engines in extreme cold other than block and oil pan heaters. I daily my classics year round and this past winter i left my LTD running for 3 days straight becuase it was minus 50 and even with those i was scared it wouldnt start if i shut it off
It's easy to blame China, but the real problem is that the buyer wants the lowest price possible and China is willing to take steps that American companies wouldn't, like hiring near slave labor, working them insane hours and shipping everything that comes off the line with little or no final inspection. And we, the American consumer, did that by abandoning products made in the US because they cost too much. And this isn't new, it's been going on for decades. Hell, we wouldn't pay for a $100 bicycle made by Schwinn in the USA and after years of holding out, they finally had no choice but sell out to China. WE did that. We're to blame.
It's not so much what the consumer was willing to pay than it is what giant retailers like WalMart forced manufacturers to do. They'd make a manufacturer totally dependent on selling at WalMart, then kept demanding the products at lower and lower prices until the company HAD to choose between moving production overseas to meet WalMart's pricing demands or going out of business
Exactly. And the only reason Walmart gets by with the garbage it sells is because we, the consumers, buy it. Stop buying junk and Walmart and others will get the message and carry decent stuff.
Agreed. In the era people fondly remember of high quality household products (like vacuums, kitchen appliances, etc.), they don’t remember or realise how expensive they originally were. The Sunbeam toaster I use daily today originally retailed in 1954 for the modern equivalent of $300 or $400, and vacuums weren’t a frivolous, stupid gift but a major expense for the home. The upside was that those things lasted. What we build now on the cheap does not.
Can you imagine what we fly in when we travel in jet planes????? It is too scary.
Somewhere in a book I read THE CHINESE ARE COMING - all that's holding them back is their quality. My observation has been, as far as quality goes, that the Chinese are about where Japan was back in the 70's and 80's in terms of the quality of the products. But, quality is something that can be learned.
Unfortunately this kind of thing is only becoming more common I just replaced a transmission mount on a power glide a month ago because the old one was Bluetooth
The new one became Bluetooth in a week
with the overseas carburetors i rebuild them even when they are new before installing them...there's always rough edges and left over flashing etc inside them...
