One possible explanation The pump economy jet could have been an easy modification for engines hooked up to generators. They rarely run at idle, so the accelerator pumps aren't really needed, you only need a few drops of extra fuel while starting it. (You also need to change the heat range on the spark plugs ) So I suspect someone used the parts list for a military generator that used the same carburetor and engine unaware that there are slight differences.
And this is why it's vital to understand HOW things work and not just follow the manuals blindly. I overhauled a batch of Solex jeep carbs ten years ago, just moved the dusty box of left overs last weekend. I remember that some of the rebuild kits had incorrect parts in them and I reused some of the old bit to make the carbs function correctly. I'll have a look and see if there are any clues in the box this weekend....
OK, just popped out to the jeep shed and had a look at the Solex box of bits. Found my notes from the time which state that I'd checked the jetting in eight used French M201 carbs before I started rebuilding the batch, to avoid any confusion/problems from the slightly random jet selection in the carb kits that the dealer had supplied. The jet you are interested in was the 110 size in all eight and not the non return valve that you (and I now) think should be there. Had a good look at a carb and agree that it will just dump much of the accel pump fuel back into the float bowl, although the 110 jet will restrict this a little. Being a bit of a packrat, I'd kept many of the old carb jets etc. in an ice cream tub and looking through them, there are some 110 jets, but no non return valves. Also got four left over damaged French carb bodies one of which still has the 110 jet. The only feedback I got at the time, was positive, no complaints. Thoughts from this? you and now I are missing something, or these carbs are all wrong and people just expect poor performance. I run a Carter on my own MB, but there are a couple of jeeps running Solexes at work, will have a look at them when I get a min.
I'm 0:37 in and I'm wondering if you're going to address all the people that complain that they can't get their flat-head powered jeeps over 35mph. I've heard it countless times and had (jeep is now repowered to 225 Dauntless) no issues hitting 60+ on the flats when my jeep was running original engine. Dude! 11:45 _HUGE_ difference! Well fucking done, mate! I just shared this over on "The CJ2A Page" forums. You're a friggin hero, mate!
Super impressive, your work and in-depth research!!!! I have a 1946 CJ2a and run the modern solex carburetor on it and call them $100 throw aways when they run to rough after about a year and buy a new one. I am restoring a 1941 slat grille and love the research and guidance you provide! Keep up the great work. You just found a jeep gold mine, need to get with a machine shop and contact them to make the one way valve and sell them $$$$
Back in the 1990’s I bought what I thought was a 1940’s CJ2 but when I scraped the paint off things, and examined the whole vehicle, turned out to be mostly a 1945 GPW, with Willy’s engine and etc. all the bolts and other Ford parts had the F script on them. Pretty fun and capable off road vehicle.
I have an original 1942 Willys GPW with a Bantam trailer. I have owned this amazing vehicle since 1982. We ditched the original Carter in about 1989.....and replaced it with a Stromberg carburettor from an Australian-made 1955 model Holden FJ......and I have never touched it since!!!!!!!!!!!!!!!!. Starts instantly, loads of power, and even excellent fuel economy...........excellent video. Greetings from Australia. Les Griffiths
Great research/demonstration. I opted for a Carter when I was restoring my 1942 GPW only because I heard bad stories about the Solex. The question now is: does anyone produce the correct one-way valve so that the economy one can be changed out?
Thanks for the quick reply. I'll hold off on a Solex until someone sees this great marketing opportunity and begins to produce a replacement one-way valve@@Greendot319
It looks like the correct one way valve is available carburatori-italia.it/negozio/solex-carburetors-pump-non-return-valve/ I have been sent the French M201 manual for 1964 and it shows the part incorrectly labeled, that means the error is AT LEAST 60 years old and it was not made by the Indians. I cannot believe the error is that old! Did the French Army really drive them like how they were in the video, I just can't believe its true!
I had a sole 32 p d s I in an older 73 bmw. I cleaned it in carb cleaner overnight. Used a small diaphragm compressor to blow out all the journals. I never could get it to run properly. Thank you officer for your revelation! So it's the claret 2 b valve that should be installed and not a a celebrator. Thank you. Very fastenating! Happy jeering! I think your a genius! Many thanks!
I had a 1974 Pontiac LeMans, with a bunch of carburetor problems, I rigged up an old Windshield Washer tank and manual squeeze bulb pump (the stock Windshield Washer pump only lasted a couple days with gasoline in it) as a manual "accelerator pump"
I can confirm the Solex 32 pbic that came on the 46 Willys I just purchased had this stupid jet in place of the one way valve. I gave up on the Solex because the rebuild kit was on back order and the throttle shaft was quite worn. So I bought a new reproduction Carter W-O. Great work finding that!
Mate, I love this channel. I have a 45 Willy’s I’m trying to fix. All your videos are excellent and keeps me excited during the hard parts of restoration
@@Greendot319 so got home, pulled that bit out and its just a brass threaded bit with a hole in it no check valve. And what's impressive about that is when I rebuilt this solex I remever hitting the throttle lever and thinking theres not much fuel at the accelerator nozzle. Also my 50 cj3a is a dog off the line, and between gear changes. Thank you, I'm gonna see if I can find a correct rebuild kit for my solex.
So I drilled my "economize" deeper dropped in a small loose ball bering from a skate board wheel bering and made a little keeper pin to hold it in place. Installed it primed the carb and wow that nozzle throws some fuel now! Did a road test and wow what a diffrenace it made!
Excellent Matt. Good work. I can hear your excitement in your voice ! Next project ? How-to get the best from the drum brake set up so the GPW actually stops.........please 😊
Thanks for being so intelligent and meticulous in finding out the problem. This is a case of Lost In Translation from the French hands to the Indians. The original shop manual of M38 is accurate.
I have a 43 and I'm an American and I live in New Jersey and I have the original carburetor Carter and it runs great I don't have any drop offs or anything like that at all
That is exactly what mine has done since I bought it in 2008 Still have the problem. I now have 3 solex carbs. Just bought a rebuild kit. Oct 24 put it in still the same. I’m going to find the one way valve. ❤❤❤❤
I don't have one. I'm not interested in getting one. HOWEVER, I loved this video. Fantastic job making an entertaining, well edited video! I'm subbing for future content!
OMG this has described my 1962 M201 to a tee. THANKYOU. when I take up power there's a Lagg. Feels like it wants to stall until I feather the gas. I will now be getting the one way valve
I had one with a siezed advance weights in the distributor due to the preservative grease drying out and getting sticky , same symtoms, once i discovered that and freed off the weights in the distributor by turning the rotor arm backwards , the jeep accelerated cleanly instead of dying out on initial acceleration , exactly the same symptoms as the missing non return pump jet shows
Well done Matt - just shows how things can get muddled - this has happened at odd times with other parts in the old car world, 3.8 E-type brake master cylinder confusion was a modern era problem (people think or thought they were the same cylinder for front and back brakes - nope)
Thanks. I now know why the carb on my wife’s Yamaha VSTAR 250 was bogging down it’s accelerator pump was stuffed. I ended up replacing the entire carb with a Chinese carb and it now runs great.
If you lifted the needle up one notch the original carb would have accelerated instantly , they have 3 or 4 groves, drop the circlip down to lift the needle giving richer mix and early fuel on accel;eration , dig out your old carb and try it
My family had an MB in the 60s and 70s. Mom gave a shoe box with some tools told me to go fix something. The only thing around was the jeep. Over the next months i took the W-0 carb apart so many times that when dad went to drive the jeep it leaked from every passage. I whipped the carb off in a minute to dads amazement and he took me to the jeep parts store. He set the carb on the counter and said my son fixed this can we buy another. The counter guys looked at the carb. Then down a 9 year old me. Dad told me that this carb does not need fixing ever. Took me 40 years to realize that he took me with him so he did not get blamed for destroying the carb. Oh the fun i had in that jeep. The city of los angeles used to plow the weeds in vacant lots. The lot next door was so much fun running the jeep over the clods to smooth them out. The jeep got restored to military spec expect for the shovel notch that i had covered with a panel . I still see it in veterans day parades in los angeles. Huge hint. Neodymium magnets with holes in the middle. A piece of copper wire looped thru the hole. Dropped inside the fuel tank. Make sure its away from the float arm. I have stuck the arm to the bottom before. The neodymium magnet attracts all the super fine rust particles to it. Keeps them out of the fuel pump check valves and needle and seat in the carb. This prevents vapor lock where the pump check valves leak and the engine heat causes the reduced pressure fuel to boil. The expanding vapor pushes the liquid fuel all the way back to the tank. I also install 10 micron fuel filters just before the fuel pump inlet. 30 to 70 micron filters won't stop the super fine sediment. Fuel injected cars get magnets too. The copper wire allows you to hook them to clean them off.
In the mid '70s you could buy Willys or Ford jeeps army surplus brand new in the parts crates for $100.00. My neighbor had a tidy little business putting them together and selling them for $500.00. He converted all of them to 12V by adding a GM alternator, battery, starter and the needed bulbs. He bought Rochester carbs from the local boneyards for pennies on the dollar and used those. They ran great but eveyone back then wanted the bigger Broncos, Blazers/Jimmys and Ramchargers so they were still a hard sell to the average person. If all that inventory were only around today.........
Man, that wasn't clickbait at all ! super cool story, you should have put an quick online store selling the one way valve, bam instant super rich ahah !
Solex carburettors were made in India for cars like Ambassador (Morris Oxford) , Premier (Fiat), Mahindra (Jeeps) etc. It was the advent of the Japanese Suzuki cars under the Joint Venture Maruti Suzuki that brought in the Mikuni Carburettors for the first time to India.
Good job and video as always. My Carter yf can have some common problems that drove me nuts but over time I've learned a lot. Your issue here was it was crippled from the start. This probably drove you crazy. Great job to figure it out
I just got a sweet deal on a 1954 jeep willys m138a1 that is bone stock with all the 24 volt water tight components. The man who owned it bought it from a government auction back in the 80's, but never titled it for the road. He passed away, and his daughter sold it to me. I live in Michigan USA, and the guy used this on his summer property in northern Michigan. The body needs some small patches that i will get from sheet metal off of a 1953 m38 that i traded 800$ worth of stuff i wasn't using in my shop. I bought the parts jeep first, and then a week later i found the m138a1 on the kaiser willys for sale site for 3000, but i got it for much less because no one wanted to drive to mid Michigan to buy it, and she would not sell it without it being seen by the buyer. I was lucky she didn't know what she had. The only thing the guy did, which isn't a problem for me, is he painted the exterior a dark maroon color. The jeep hasn't been run since 2017, but the motor turns freely, and it was stored inside. He stopped driving it when he was in his mid 80's because he could no longer get in and out of it. I paid to have it taken to my house by a flat bed tow service, and the guy said he wished he'd have known about it because he would have bought it. I guess it got a lot of thumbs up on the two hour drive to my house. The tow truck driver asked me to send picture's of it when it's done. It won't be done overnight, because i want it to be right, and that's not cheep as you know. These old military jeeps were built heavy, not like today's vehicle's. I have extra drive train parts from the 53, and those parts are good. I am 53, and have restored a couple classics in the past, but i have always wanted one of these jeeps, but never could find one good enough in my area. I just subbed to your channel, the tube suggested one of your video's. I have watched several of your video's, and like the content. I am probably one of the two woman who watch lol. As a kid i was older than my brother, so i was the free child labor for my dad and grandparents, who taught me how to wrench, and build stuff. I like being busy, and love working on car's. Both my grandpa's were in wwll, one was a medic for 4 year's and was at d-day, and the other was a anti tank artillery sergeant and also did demolitions with the engineer's. My grandpa had a 53 military jeep when i was a kid, but sold it to my uncle before he died, loved going for rides in it. We used to drive a1967 mule around his farm, wasn't real fast, but it went through the woods well enough. Sorry to type so much, but most of my family are gone, and i don't really have anyone to tell about it. Nice jeeps you have, glad these old rigs are being restored. G-d bless.
Volvo boat engines used solex carbs hp rating change by how many carbs the engine had sometimes synchronizing the carbs could be a pain if you didn't know what you was dodoing
Just swap it out for a Stromberg 97. That terminology was changed for a specific reason & the physical part was changed also (economy jet). Why is the ? & who's behind it? Great video.
Hi yes I have a economy jet on my French army jeep and a solex Indian made carburettor with solex cast in the top cover where to get the one way valve thanks colin
I wonder if this is a similar problem I experienced with the simple Rochester carburetors for my 6 cylinder Chevy Belair. Even after replacing the carburetor with overhauled ones twice I experienced a very similar problem with the accelaretor pump. After replacing it again the problem is now hardly existing.
they charge just a few pounds , Pa Blanchard& co , ask for a non return pump jet for solex 32 pbi - 2 lb56 carburettor , replace your economy jet with the non return valve , you can do it in seconds no need to take off the carburettor , its located directly under the eccelerator diaphram, 12mm ring spanner fits it
I took 12 carbs apart and out of 12 found one with the non return valve, I have photographed it and sent the pictures to the carb kit suppliers , I cant send a picture on this feed sadly
My dad had a dodge aspen and he got the carb rebuilt twice before i took it apart the third time it failed and found the accelerator pump piston seal had flipped over bucause of swelling from the alcohol in the gas. It was a long time ago and i think i found a piston with a leather seal which aolved the problem.
There is a company in the Philippines that manufactures and sells "Jeep’s in a box". If you can come up with a drivetrain of some sort to fit the frame you can build yourself another one. Check with your states DMV as to what is needed to license it in your state as a "home built". Usually headlights, tail lights, brake lights, backup lights, signal lights, horn, windshield wipers are the most common items needed. Some states will even require seat belts but they never came with the original Jeeps.
Super simple... and yet that bodge fix in the design for one issue takes of 1/3rd of the mass of the carb 😕 I h8t3 all these tiny holes, they get clogged up and then your carb stops working.... I have trouble with my idle jet hole all the time getting clogged, and then your engine runs like junk.
make sure you have the carb float bowl cleaned out and a lift pump with the fine gauze cap fitted inside the dome cover , if your using an electric pump put a modern disposable replacable filter in the line close to the carb , that should stop that tiny idle jet blocking but its an easy fix if it does block as its externally accessable and a few seconds to unscrew it with a 8mm spanner while the carb stays connected to the jeep
Thank you for this great information. Were in the uk could i get one of the correct type to fit, Have you got any good suppliers or website to go too . so we all can have a jeep running as they show be . Thank you and keep this great information coming 👍
You are an amazing researcher and problem solver. I appreciate your desire to achieve authentic, not perfect. There is a difference and I doubt any jeep was perfect off the assembly line. I can't find the valve on eBay using the number you gave. Any other clues to obtaining the correct valve?
There are a number of carbs out there (nothing to do with Jeep's) where the accelerator pump is calibrated with a jet back into the float chamber (your pump economy jet) It doesn't look like you have an accelerator pump delivery jet, and just have the brass tube, unless the brass tube can be changed in size. The amount of fuel delivered to the engine by the accelerator pump can be controlled by changing the diameter of the pump economy jet, so are there different size pump economy jets available? I would say the change might have been made as a production easement modification (ie money saving). Its got to be cheaper to make than the original ball design. Also modern fuels are much different to the WW2 stuff so that could also exacerbate the problem.
Thanks for the comment, the carb also has a calibrated pump jet that is briefly mentioned in the video, it is fitted downstream of the pump and the one way valve to meter the amount of pumped fuel.
ok so if you have changeable pump delivery jets then that is the way the accelerator pump is calibrated. I saw the spring on the pump linkage so the force to work the pump comes through the spring. So if you quickly mash the throttle you don't damage the pump. The amount of fuel the pump delivers is dictated by the size of the pump so in theory the smaller the pump delivery jet the longer the duration of the "squirt" but also with the economy jet and with a smaller pump jet the more of the fuel will be pushed back into the float chamber so the pump jet and economy jet are essentially working as a pair. All this said though you seem to have solved the problem with the ball valve.@@Greendot319
they got it right by chance, they just copied the right parts diagram , they dont have the time or resources to go reserching the solex carburettor , they just bang out thousands of copies of what ever they get asked for , hats off to them but often they have made thousands of somethinmg before checking it fits then by the time its discovered we all have duff unusable parts on our shelves, a they use bit of quality control in China before sending the parts off and they will dominate the world
just one comment on your water radiator clamps you should throw those nasty ones you have that have a sharp screw sticking out to an all-SS (stainless steel) one they go for around $2 a very small investment to i see on top you got 4 that needs throwing out and I don't know how many on the bottom, you can also turn it round were you only see the SS band a really cool look
absolutely agree, the origional hose clips are primative and often cant be tightened up enough to stop leaks , the patented jubilee clips can be purchased in standard or stainless steel and will go real tight , no more leaks , but I guess its a purist thing and what the purists will be prepaired to put up with to keep things looking original is begger belief
Just out of curiosity, why do you use the Solex rather then the Carter WO? Do you prefer Solex? My Carter works well, but can be a bear to adjust at times. Was thinking of trying out a Solex on my 42 GPW, to test for “user friendliness. Cheers.
The Solex 32AIC is an absolutely fantastic carb for the jeep, very smooth idle, great power and it doesn't have a mechanical accelerator pump so it has the best throttle response and acceleration of any carb but it is fiddly if you don't know its doing. It will only start a specific way when hot or cold and suffers from fuel percolation but because I know how to deal with it it is worth it, for the average user it would be more hassle than its worth compared to the practically bullet proof Carter.
One possible explanation
The pump economy jet could have been an easy modification for engines hooked up to generators.
They rarely run at idle, so the accelerator pumps aren't really needed, you only need a few drops of extra fuel while starting it.

The counter guys looked at the carb. Then down a 9 year old me. Dad told me that this carb does not need fixing ever. Took me 40 years to realize that he took me with him so he did not get blamed for destroying the carb. Oh the fun i had in that jeep. The city of los angeles used to plow the weeds in vacant lots. The lot next door was so much fun running the jeep over the clods to smooth them out. The jeep got restored to military spec expect for the shovel notch that i had covered with a panel . I still see it in veterans day parades in los angeles. Huge hint.
Neodymium magnets with holes in the middle. A piece of copper wire looped thru the hole. Dropped inside the fuel tank. Make sure its away from the float arm. I have stuck the arm to the bottom before. The neodymium magnet attracts all the super fine rust particles to it. Keeps them out of the fuel pump check valves and needle and seat in the carb. This prevents vapor lock where the pump check valves leak and the engine heat causes the reduced pressure fuel to boil. The expanding vapor pushes the liquid fuel all the way back to the tank. I also install 10 micron fuel filters just before the fuel pump inlet. 30 to 70 micron filters won't stop the super fine sediment. Fuel injected cars get magnets too. The copper wire allows you to hook them to clean them off.
Wow! Sounds like you've solved vapor lock. Sounds like great idea. Koodos to you Sir. Also.
Great update, well done for finding the solution!
Thank you, I couldn't believe it when I finally worked this problem out. What a mistake to make!
Great detective work, Matt!
Not had any issues with my Solex fitted MB , however very interesting video , Thanks muchly
No problem that's good to hear! Not all will be affected so if it works it works! enjoy
Similar to the 32PICT on my 68 Beatle. As you say, no pump, no go.
Yep, really important
Brilliant mate. Well done. I did think it was going to be click bate, but no not at all.
Brilliant work. Well done 👍
Well ok then!
Similar has happened with the replacement carbs for the Farmall cub tractor
I have a solex in my stores I will check this out . Great vid Matt
yep have a look and also see if its an older looking one or a newer looking one. Looks like the issue has been round since the 60's!
I hope you’re well mate, hopefully been spending time with your fam. Cheers
😊 Great video 🙂
In the mid '70s you could buy Willys or Ford jeeps army surplus brand new in the parts crates for $100.00. My neighbor had a tidy little business putting them together and selling them for $500.00. He converted all of them to 12V by adding a GM alternator, battery, starter and the needed bulbs. He bought Rochester carbs from the local boneyards for pennies on the dollar and used those. They ran great but eveyone back then wanted the bigger Broncos, Blazers/Jimmys and Ramchargers so they were still a hard sell to the average person. If all that inventory were only around today.........
Man, that wasn't clickbait at all ! super cool story, you should have put an quick online store selling the one way valve, bam instant super rich ahah !
I mean who said it was going to be clickbait lol 🤣
Great video and investigation!!! Sherlock Holmes himself couldn’t do better. Well done !
Great discovery, thanks for sharing (even if I don't own any jeep)!!!👍👍👍
Yaahh … same here. Not the correct valve so I have ordered the correct from the Italian carb-site. My Solex is a brand new bought from Jeep Sudest.
Solex carburettors were made in India for cars like Ambassador (Morris Oxford) , Premier (Fiat), Mahindra (Jeeps) etc. It was the advent of the Japanese Suzuki cars under the Joint Venture Maruti Suzuki that brought in the Mikuni Carburettors for the first time to India.
Great work Matt....That would make a huge difference....
Yep if it affects your carb it looks to be important
I’m jealous of how well your jeep runs and drives. I need to buy a new engine some day
I know it is not a sports car paint job, but I would be using fender covers on such a beautiful classic.
Good job and video as always. My Carter yf can have some common problems that drove me nuts but over time I've learned a lot. Your issue here was it was crippled from the start. This probably drove you crazy. Great job to figure it out
Just out of curiosity what are the actual issues with the Carter YF carburetor?
I just got a sweet deal on a 1954 jeep willys m138a1 that is bone stock with all the 24 volt water tight components. The man who owned it bought it from a government auction back in the 80's, but never titled it for the road. He passed away, and his daughter sold it to me. I live in Michigan USA, and the guy used this on his summer property in northern Michigan. The body needs some small patches that i will get from sheet metal off of a 1953 m38 that i traded 800$ worth of stuff i wasn't using in my shop. I bought the parts jeep first, and then a week later i found the m138a1 on the kaiser willys for sale site for 3000, but i got it for much less because no one wanted to drive to mid Michigan to buy it, and she would not sell it without it being seen by the buyer. I was lucky she didn't know what she had. The only thing the guy did, which isn't a problem for me, is he painted the exterior a dark maroon color. The jeep hasn't been run since 2017, but the motor turns freely, and it was stored inside. He stopped driving it when he was in his mid 80's because he could no longer get in and out of it. I paid to have it taken to my house by a flat bed tow service, and the guy said he wished he'd have known about it because he would have bought it. I guess it got a lot of thumbs up on the two hour drive to my house. The tow truck driver asked me to send picture's of it when it's done. It won't be done overnight, because i want it to be right, and that's not cheep as you know. These old military jeeps were built heavy, not like today's vehicle's. I have extra drive train parts from the 53, and those parts are good. I am 53, and have restored a couple classics in the past, but i have always wanted one of these jeeps, but never could find one good enough in my area.
I just subbed to your channel, the tube suggested one of your video's. I have watched several of your video's, and like the content. I am probably one of the two woman who watch lol. As a kid i was older than my brother, so i was the free child labor for my dad and grandparents, who taught me how to wrench, and build stuff. I like being busy, and love working on car's. Both my grandpa's were in wwll, one was a medic for 4 year's and was at d-day, and the other was a anti tank artillery sergeant and also did demolitions with the engineer's. My grandpa had a 53 military jeep when i was a kid, but sold it to my uncle before he died, loved going for rides in it. We used to drive a1967 mule around his farm, wasn't real fast, but it went through the woods well enough. Sorry to type so much, but most of my family are gone, and i don't really have anyone to tell about it. Nice jeeps you have, glad these old rigs are being restored. G-d bless.
Good catch. I run a Carter but if I encounter a Solex that's a handy bit of info to have.
Carter is a great carb, its accelerator pump can cause problems too if not set up correctly but that's the same as anything else!
I like your jeep. I have a two door JL. I Love My Jeep!
Volvo boat engines used solex carbs hp rating change by how many carbs the engine had sometimes synchronizing the carbs could be a pain if you didn't know what you was dodoing
Just swap it out for a Stromberg 97. That terminology was changed for a specific reason & the physical part was changed also (economy jet). Why is the ? & who's behind it? Great video.
Hi yes I have a economy jet on my French army jeep and a solex Indian made carburettor with solex cast in the top cover where to get the one way valve thanks colin
The Solex for the early land rover has the correct valve.
Correct land-rover uses PBI-2 with the economy jet, 32 PBIC for the jeep does not. Somebody got confused!
Well done. Thanks for the education!
Thank you sir. My 1944 Willys MB thanks you as well.
You are welcome
Good video easy to understand and well done!
6:44 the lady at the back thinks the allied have landed again.....
she thinks she's been eating mushrooms again
Thank you for the Vid, maybe this is exactly the issue of the jeep from a buddy
I wonder if this is a similar problem I experienced with the simple Rochester carburetors for my 6 cylinder Chevy Belair. Even after replacing the carburetor with overhauled ones twice I experienced a very similar problem with the accelaretor pump. After replacing it again the problem is now hardly existing.
Excellent sleuthing on your part!
Thank you!
they charge just a few pounds , Pa Blanchard& co , ask for a non return pump jet for solex 32 pbi - 2 lb56 carburettor , replace your economy jet with the non return valve , you can do it in seconds no need to take off the carburettor , its located directly under the eccelerator diaphram, 12mm ring spanner fits it
With your roads and with all those blind intersections, you REALLY NEED a carb that is working properly.
I rebuilt my 32 PBIC a few years ago, pretty sure it has the economy jet. I’ll have to check. Where do we get a one way valve if we need one?
I love this so much! What a crazy adventure.
Excellent research/solution and video Matt, thank you very much sir. 😃👍
Very welcome
Any new videos 🤔?
Nice!! Very interesting
But to be onnest, i keep it to my Carter carb 😉
Yep, its a good carb
Amazing, thank you for your in-depth research, it helped us all
Nice catch !
Thank you very much!
I took 12 carbs apart and out of 12 found one with the non return valve, I have photographed it and sent the pictures to the carb kit suppliers , I cant send a picture on this feed sadly
My dad had a dodge aspen and he got the carb rebuilt twice before i took it apart the third time it failed and found the accelerator pump piston seal had flipped over bucause of swelling from the alcohol in the gas. It was a long time ago and i think i found a piston with a leather seal which aolved the problem.
There old style on a old style side valve with modern type fuel .I went turbo diesel for using everyday no worries
Awesome. Well researched and well done 👏
Many thanks for your support
Nice channel! When are you uploading new videos?
Where is the jeep reg # BTK 105 it was totally restored some years ago ,if you know it i have some fond memories of it 😊😊
Sorry I do not know
Outstanding work!
absolutely crazy the work you have done!
Great research truly valuable information, and your jeep really does look amazing, miss mine when I see your videos 😢 keep em coming 👍
Thanks very kind. Jeep is best vehicle to own
There is a company in the Philippines that manufactures and sells "Jeep’s in a box". If you can come up with a drivetrain of some sort to fit the frame you can build yourself another one. Check with your states DMV as to what is needed to license it in your state as a "home built". Usually headlights, tail lights, brake lights, backup lights, signal lights, horn, windshield wipers are the most common items needed. Some states will even require seat belts but they never came with the original Jeeps.
Had a new solex on my m38 i hated it, rebuilt a wo and problem gone, this might be what was wrong with it, maybe I'll try it on the gpw...
make shore your diaphram is good and flexable not gone stiff or perforated with age otherwise fitting the one way valve wont make any difference
Super simple... and yet that bodge fix in the design for one issue takes of 1/3rd of the mass of the carb 😕
I h8t3 all these tiny holes, they get clogged up and then your carb stops working.... I have trouble with my idle jet hole all the time getting clogged, and then your engine runs like junk.
make sure you have the carb float bowl cleaned out and a lift pump with the fine gauze cap fitted inside the dome cover , if your using an electric pump put a modern disposable replacable filter in the line close to the carb , that should stop that tiny idle jet blocking but its an easy fix if it does block as its externally accessable and a few seconds to unscrew it with a 8mm spanner while the carb stays connected to the jeep
Thank you for this great information.
Were in the uk could i get one of the correct type to fit,
Have you got any good suppliers or website to go too .
so we all can have a jeep running as they show be .
Thank you and keep this great information coming 👍
I have the 110 purchased it in 2016 went back to a carter
You are an amazing researcher and problem solver. I appreciate your desire to achieve authentic, not perfect. There is a difference and I doubt any jeep was perfect off the assembly line. I can't find the valve on eBay using the number you gave. Any other clues to obtaining the correct valve?
Just a question what sort of petrol do you use in your jeep
lowest ethanol possible which in the UK now is 5%
@@Greendot319 thanks 👍
Its not the fuel , jeeps will even run on parafin when warm and everything set up right
There are a number of carbs out there (nothing to do with Jeep's) where the accelerator pump is calibrated with a jet back into the float chamber (your pump economy jet) It doesn't look like you have an accelerator pump delivery jet, and just have the brass tube, unless the brass tube can be changed in size. The amount of fuel delivered to the engine by the accelerator pump can be controlled by changing the diameter of the pump economy jet, so are there different size pump economy jets available?
I would say the change might have been made as a production easement modification (ie money saving). Its got to be cheaper to make than the original ball design.
Also modern fuels are much different to the WW2 stuff so that could also exacerbate the problem.
Thanks for the comment, the carb also has a calibrated pump jet that is briefly mentioned in the video, it is fitted downstream of the pump and the one way valve to meter the amount of pumped fuel.
ok so if you have changeable pump delivery jets then that is the way the accelerator pump is calibrated. I saw the spring on the pump linkage so the force to work the pump comes through the spring. So if you quickly mash the throttle you don't damage the pump. The amount of fuel the pump delivers is dictated by the size of the pump so in theory the smaller the pump delivery jet the longer the duration of the "squirt" but also with the economy jet and with a smaller pump jet the more of the fuel will be pushed back into the float chamber so the pump jet and economy jet are essentially working as a pair.
All this said though you seem to have solved the problem with the ball valve.@@Greendot319
if you blow and suck through the one way ball type jet it only allows one way travel so no wash back can happen
Wonderful content!
Really good explaination. I love that the chinese knock-off's got it right .. I don't have the words but can't stop smirking.
they got it right by chance, they just copied the right parts diagram , they dont have the time or resources to go reserching the solex carburettor , they just bang out thousands of copies of what ever they get asked for , hats off to them but often they have made thousands of somethinmg before checking it fits then by the time its discovered we all have duff unusable parts on our shelves, a they use bit of quality control in China before sending the parts off and they will dominate the world
just one comment on your water radiator clamps you should throw those nasty ones you have that have a sharp screw sticking out to an all-SS (stainless steel) one they go for around $2 a very small investment to i see on top you got 4 that needs throwing out and I don't know how many on the bottom, you can also turn it round were you only see the SS band a really cool look
But that would be using un-original modern parts though wouldn't it ?
absolutely agree, the origional hose clips are primative and often cant be tightened up enough to stop leaks , the patented jubilee clips can be purchased in standard or stainless steel and will go real tight , no more leaks , but I guess its a purist thing and what the purists will be prepaired to put up with to keep things looking original is begger belief
Which would you recommend
Just out of curiosity, why do you use the Solex rather then the Carter WO? Do you prefer Solex? My Carter works well, but can be a bear to adjust at times. Was thinking of trying out a Solex on my 42 GPW, to test for “user friendliness. Cheers.
The Solex 32AIC is an absolutely fantastic carb for the jeep, very smooth idle, great power and it doesn't have a mechanical accelerator pump so it has the best throttle response and acceleration of any carb but it is fiddly if you don't know its doing. It will only start a specific way when hot or cold and suffers from fuel percolation but because I know how to deal with it it is worth it, for the average user it would be more hassle than its worth compared to the practically bullet proof Carter.
