Just got a 05 Yamaha bruin 350 in excellent condition. After about two weeks of riding, it started sputtering and bogging out when I give it gas. Took carb apart to clean and it was like brand new inside, but I cleaned anyway and replaced sparkplug. Put carb back on and same problem. If I slowly give it gas it'll slowly pick up rpms and fly but as soon as I decrease gas and begin to increase again I get the same sputtering like it's starving for gas or getting to much. Like I said, this machine hasn't been taken care of very well and has less than 1000 miles. It also will backfire a little bit every once in a while after I get off gas at high speeds. Need help
Being a 2 stroke the crankshaft seals may have dried out over time and is coursing an air leak around the crank. Check all gaskets and crankshaft seals as you don't need to hole a piston with a lean fuel air mixture. Take care and good luck 👍
Thank you so much. Wonderful explanation and you helped me fix my Yamaha 350, was running rough and spluttering on high acceleration. Runs like new. Again thank you 🙏
Iva a Kawasaki KLF 300 that won’t start !! It was originally just getting slower and slower to start, so I stripped carb and replaced all needles and jets etc , I found someone before me at left in too many rubber rings and washer on pilot air screw jet , but now after re-assemble it won’t fire at all ?? Just seems to back fire through carb a little bit , I’ve good fuel and I have spark , I’ve tried spraying into carb while cranking to see but still no fire ????
i have the same issue with my recently purchased kawasaki brute force 750 atv. Seller told me it ran great and had the carb cleaned and re jetted by a local shop just before he put the bike in storage for the winter season. When i showed up to buy it, it spitted and sputtered like crazy and would not stay running. After i rode it around a little bit i raised the choke level up about 15% and it seemed to run fine then...the idle was great and no more sputtering or spitting. Seller was shocked and told me it ran perfectly before he stored it for the winter. I went ahead and bought it anyways knowing it was fixable no matter what and he gave me a killer price on it so I was still stoked to buy it. I so far am just riding it with the choke partially open and it runs fine so far that way at least.
colourtune plugs are handy as you can check the color of the flame which should be Bunsen blue after the choke is pulled in. there is a mixture screw under the carb usually which you can screw out a turn to get more fuel...might be worth a try. As long as the jets are the correct ones and the float heights are correct then with a clean carb the bike should run well.
This is indeed a brilliant explanation ever to my Yamaha AG 200. By looking at this vedeo I've also checked and cleaned the main horse's nipple from the fuel tank to the cab which was being blocked by so many dirts. 2 Problems that were solved are engine dies when at low RPM or when at higher RPM, and hard starts again at about 3 minutes. ❤❤
Thank you! Having a heck of a time with my 125cc sputtering and definitely not idling. Always has run great previously. I cleaned out the carb but will re-check these side ports. I’ll let you know if it works!
This was probrably one of the best videos about small carbs thank you so much I dont think Anyone could have explained that any better video was straight to the point.. Ive been struggling with a small carb. First it was leaking out the over flow then it was backfiring thru the air intake now its bogging down with throttle doesnt die starts right up but bogs way down driving me crazy but im pretty sure after dozens of videos this is the video i needed to see. Will let you know thanks again
im going to try this today. i have an old 1991 honda 300 fourtrax that seems to carbon plugs almost instantly. the bike idles great and can putt around in SL no problem, but as soon as your on the throttle to get through your gears, its as if the mid range power is completely gone it struggles to accelerate, and it starts to come back in to normal in the high end RPM. its causing jerky acceleration through gears and when finding your cruising speed. ive taken apart the carb and cleaned the jets, along with replaced the air and oil filters, plug and oil. somewhat fixes the problem but reverts back (my guess once the plug fouls) im starting to think the float may need to be adjusted now, thanks for the new lead!
Man runs perfect in every gear when you put it in reverse it don't have no power it just spits and sputters will not go backwards I also bought a brand spanking new carburetor and put it on it and it run perfect but like I said when you put it in reverse it just spits its better it won't go backwards unless you're on flat ground
Thank you!!! I am a complete noob and just started getting into ATV’s last summer. I am currently on my pulling carb for the 7/8 time done yesterday. the same carburetor in and out with out luck This video may be my saving grace
What kind of atv are you working on? And did you try this yet? Having problems with a 2004 predator 500 stalls at idle. I’m going to try and pull the carburetor this weekend.
Best explanation yet. 2 out of four are doing this. I'm on it. Thanks. The 99 honda 300, never a problem. The rubicon 472, both have this issue. Was puzzling. Will follow.
I have a 2004 Can-Am we had to clean the gas tank and all that out. I was having trouble with the original carburetor. We think we cleaned it out properly but would not work. It was getting too much gas so I bought a Chinese carburetter and it’s still doing the same but running, a whole lot better but still not not running right should I just buy? Another Chinese carburetter Maybe I got junk one PM me if you can
I have a situation that's very confusing, I took a ride into a patch of woods on my 2017 Polaris 450 HO for maybe thirty minutes-there was no path so I was running over trees big and small-I made it out of the woods but at the treeline, my engine started running rough, sputtering, backfiring. Luckily, I made it back home at a crawl while cranking the throttle back and forth, I had a new plug -OEM- so I switched it out- never did see the carb to see if I pulled anything loose, the plug didn't help much. I lifted the front end up so I could check out the bottom side, saw nothing pulled loose or hanging. That's my situation and any help would be appreciated
Question, I just bought a 1994 Kawasaki Bayou 220 and the starter sounds horrible. I replace the starter with a brand new one off of Amazon and the starter sounds exactly the same and it’s almost like a grinding sputtering noise and it sounds like the starters not getting enough power to crank the four wheeler. Any ideas?
Hi . Thomas thank you for the info, i have an issue with 2006 ktm 50sx with stock carb and jet Dellorto carb brand. cleaned carb. as you said. 4,x. it boggs down at full throttle bike on stand. 60/1 fuel ratio. im in california 40 miinutes inland from beack. so u get idea on elevation. i appreciate ur help
That’s crazy I was looking at buying a 2008Q link 700 front runner side-by-side with a sputtering issue in the first video. I find covers my ATVs issues I have a 400 Polaris and I’ve been struggling with the sputtering issue so now that took care of that problem.
I have a 1976 Sachs engine, Sparta buddy moped, 49cc. I pulled the old carb apart and the slide was ready to breath in half. I got a new keign carb and installed it. The moped starts fine, pulls hard, but breaks up at full throttle? Any suggestions... Thank you.
I have a Farmall 100 tractor that fires up with no problem. Then it starts sputtering and puffing smoke out the exhaust like it's flooding or choking. After doing this for several minutes, the engine will finally die. But, I can pull the starter and it will immediately fire back up with no hesitation before repeating the same issues as before. When it is sputtering, the rod leading from the carburetor will move back and forth instead of staying stationary like you would expect. Do you have any ideas as to what may be the cause of my issues? I inherited the tractor from my late grandfather and have some mechanical experience, but am in no way a professional. Any advice you could provide would be greatly appreciated!
I have a 2001 Yamaha Kodiak that starts up fine and runs but if I let it idle after a few minutes it will stall. If I put the choke on just a little it runs fine. It also will pop or backfire a little if I rev it. Ty
I've got a 1962 Ford 3000 tractor with a Holley R3655A carb. I have removed it and am in the process of cleaning and installing a kit. However I can not get the plunger to come out of the little tower it is in. I've had it soaking in carb cleaner for days and it will not pull out. Do you have any tricks for that before I attempt to drill it out?
I have a 98 yz250 2 stroke. Previous owner must have hit something very hard because the front rim was so bent that when moving it, the tire would rub the front shocks. I'm having a similar issue. But mine is occurring as I'm hitting the powerband. The bike will act like it's starving for fuel and after a few quick twists of the throttle it'll go back to full power - resulting in the front wheel coming off the ground. I'm going to pull the carb off this weekend and give it a good cleaning. Fingers crossed that I find some green goo. Otherwise I might be looking towards checking out the power valve. I'm new to 2 stroke dirt bikes/ bikes in general. I purchased it 2 months ago and have slowly been replacing parts. I'm a diesel mechanic and love tinkering with small engines. I'm open to any suggestions.
Is it normal for the carb floats to be stuck in the bowl? Is this the design? Never seen that before. I have a 1982 yz125j that keeps flooding the cylinder and plug. Can you make a video on that cause and fix?
Great video. I succeeded in rebuilding both carbs on my 1997 Polaris 500 snowmobile thanks to this video. Reassembled carbs on machine and fired it up. The mag cylinder is not drawing in the fuel, thus the mag cylinder is not firing. Suggestions?
In the bowl, should the idle jet be below the fuel level....in the fuel. No float level specs, No name carb. Not a single marking on carb. Thanks in advance
Thanks man. Just bought my first carberated bike and want to learn as much as i can about it so i can wrench on it myself. It spits occasionally, its about 40 degrees out here in colorado, and it apears to only do it when choke is all the way in... so it may just need to be dyno tuned... apparently again... not sure if its tuned for this elevation. Assumed it was and that may be a mistake as i should have asked and the dealership may have shipped it up from elsewhere.
Hey man. Love your video my mate has 150cc pitbike. He had no air filter. I make him get air filter. Bike runs bad with air filter. We clean side of jets and all carb. Bike still runs OK when take off air filter. I have try to adjust air fuel mix screw but it is always lumpy in the top end and try’s stalling
Well done 👍 But please my I say something Carburetors, engines do not suck air or fuel. Atmospheric pressure does the work, ie at sea level it is 1 bar = 14.7 LBS =Atmospheric pressure. I understand it's easier to explain that an engine sucks but it is Atmospheric pressure that pushes the air into the carburetor and fuel into the conbustion chamber as the piston goes down the stroke. Anyway I am positive that you have helped many a person 👍👍
I have a taotao 125cc Dirtbike. The carb it doesn’t run great with unless it’s in higher rpm. Whenever it is idling I have to feather the throttle to build the rpm before going. If I just hit the throttle from idle it bogs down and dies. It’s super annoying to ride because of this. Also the piston was on wrong with the intake and exhaust sides flipped since I fixed that it does run better but still is the same bogging problem. I’ve adjusted the carb so many times but to adjust the air fuel screw I have to take it off and it’s annoying taking off over and over
Question for, Im helping a friend with a polaris 500 predator carburetor issue, the initial complaint was only start and run on choke, would not accelerate but stumble flat out upon trying to increase rpm. He brought the carburetor to me, I opened it up found a plugged main jet and slightly plugged pilot jet / emulsion tube, all clean now and reinstalled, now it will start on choke and idle off of choke but as soon as you try to accelerate it stumbles flat , the diaphragm slide does move up but kind of bounces as it stumbles to rev up... What is going on here, no vacuum leaks on the intake boot either...
I have a skidoo that dumps fuel out the side tubes on the one side but how do you take the plastic pieces out of the side i broke one of the hose fittings off its all plastic one on each side
I've done all that can you let me know we're my mixture needle needs to be? The carb needle fell and I put the e clip on but can't find the right mixture with the neddle
Like the video and so correct, I have a polaris Razor that was cleaned and I took the entire thing apart. I started the engine and adjusted the air fuel screw along with the idle screw. The engine idles but will not accelerate without popping and spitting. I have adjusted the needle through every setting, please help
I have a 04 kfx 50 quad I just got done cleaning it all out had a lot of build up in the carb white residue . I put it all back together but it just doesn’t throttle up quick almost like bogging out and not reaching full throttle what could it be
I have a 1997 Honda shadow 600 I am a new rider and don’t know much about bikes yet. Bike starts up fine and runs well up until 40mph then it starts to sputter and not accelerate past 50mph, the bike struggles to go any faster. I put sea foam in about 3 days ago, 50 miles and it still does the same thing.
I have a problem with the kawasaki klf250 carburetor dismantled, cleaned, set according to the instructions, fires ok, drives ok, the problem shoots from the exhaust when releasing the gas, the candle has a metal color
The carb on my 80cc bicycle engine is bogging and backfiring out the carb and I’ve completely cleaned the carb and replaced the spark plug what else could it be
Me and my dad are working on a clients Yamaha TT-r230. He had let it sit for number of years. We had put a lot of new parts on it and still can’t get low rpm’s. Starts and idles perfect and all the power at top end. Just no low end power just stutters and wants to stall. We flushed the tank servile times. We all so put a new pepcock, fuel line, carburetor and battery on it. We have tried tuning the low end jet and nothing makes a difference but if we pull the choke 1/8 the way out. It will run like a dream. Can any one help us and shed some light for us please? Thank your guys.
i have a 32mm cvk carb. idles great. once i crack throttle, no power and just popping. carb is clean. what would u suggest. bike is a 232cc 2 valve powered taida gy6. if that matters. 600 above sea lv
On a 03 KTM 450 after complete top end rebuild , cylinder re sleeve, new piston & new titanium valves and new adjustable accelerator pump with every thing tuned and running perfect. one day after a few months my muffler started melting my side plastic muffler cover, then a few days later the bike starts to lose power at higher RPM. Any ideas ? Thanks for any help on this. Carb is KEIHIN FCR-MX 39 Carb jets stock 170-40, in shop book 175-48 Jets In as of 03-22 - 178/50
I have a 125cc venom quad brand new .Have problem starting I use choke when cold it takes a few cranks starts but if touch throttle it quits and I notice fuel coming up in the cap hose .I set the air fuel at 2 turns and do the idle screw and some times it allows throttle but most times not as I say brand new quad.?
I could not figure it out. My new motorcycle only has 200 miles on it. Came with a carburetor I have to work to get the screws off the bowl. No biggie. Yet it puzzled my on what it was doing. Did not make sense. Now it does. So, I'm going to do exactly what you suggest. I will see. If works, you just saved me money and a big headache. Thanks for your help.
Makes perfect sense. But why would my gy6 motor be running very hot. After a needle cleaning in the carb and valve adjustment? Please help me. I can't afford to have my engine seize!🙏🙏 i need it for work!!please help me out???!!🙏🙏🙏🙏
I'm having this problem, but it's a new carburetor, it was my first motor kit and I bought a zeda 80 when it was in stock, so I started a bike build for my son with my first motor similar to the PK 80 on a occ chopper bike everything is offset to the left cause of the wide bike tire, well my issue doesn't seem to be the carburetor, and being that the exhaust system is a flex tube pipe could that be a problem why it spitting and sputtering.
I have a KTM 2017 xc300 i cleaned my carb but it hadn't stop spluttering idk what else can I do. I'm going to chek the float needle. I already cleaned the jets and also the idle jet. I completely removed them and poke them like you did in the video. Please help
I have a 2008 Suzuki DRZ 125 and I can usually kick it over. Though when I turn the throttle it does not return to idle but it keeps going up or staying if what you just turned the throttle could you help me of what is going on?
Mxz 700 2001 starts n runs good and all of sudden it starts backfiring, changed choke lines, cleaned the carb too, just wondering if the choke has something to do with it, starts backfiring like crazy!
I have an old motorhome. It is back firing through the carb. Flames go everywhere. A good friend of mine got burnt badly when the same thing happened to him while working on his motorhome. I want to get the motorhome fired up. Usually requires a squirt of starter fluid and a bottle and hose with some gas in it to keep it going. Any way to keep the back fire 🔥 from catching me or the motorhome on fire?
Hi Thomas, I have some questions I'd like an answer for. I have 1995 summit 670 with vm40 mikuni carb, everything is squeaky clean almost spotless in there everything new except for needle jet and needle. (needle valve, seat, main jet pilot jet, gaskets) and had it set up to factory such as round slide opening air screw and idle screw float arm adjusted to 19.6mm bottom of the arm to face of carb where gasket sits. carb was keep flooding I tried to have float arm to 20.5mm didn'tdo it. flipped the arm set it to the height still flooding. I took the slide out and excessive amount of fuel was coming out from main jet( throat I think), thru jet needle tube. I blocked the jet with needle and tried again and breather hole and such was puking out fuel. why would it be keep flooding? and its happening to both of carb and I dont know if floats will go out at same time
You make a whole lotta sense bro! I'm having the same sputtering symptoms, only I have a Harley 2009 cvo fatbob with electronic fuel injection and what you just explained with the example with a carburetor is the same in nature, "Thanks big guy and be safe!
got a 2007 polaris atv 500 efi. starts but bogs when adding throttle. replaced fuel pump, fuel strainer, injectors, everything fuel related all the way. no change, when i put my hand over the carb, air intake it seems to rev up fine. any ideas?
Polaris 400 2 stroke I put new carb on it want idle and wants to bog down when driving at full throttle I have leaned and richen the carburetor nothing has changed. Can you please help?
Helloe Thomas. got a Raptor 350. (little story) bought it in bad shape. but it started and idled perfectly but i couldnt rev it (died) found the choke was corroded stuck so i got it loose and changed the sparkplug. wouldnt start. cleaned the carb, now it backfires ALOT(when revving too). it wont idle nice, either i rev it to keep it running or use the choke so i idles high. and it pops through the intake now. seems like everything became a mess with it. do you know what could be wrong here?
my friend bought suzuki an125, it is 4t but with 2t carb. We cleaned it very well every part and every hole but that damn carb sucks so much fuel and it needs so much air at that level we should not put air filter. One more the problem is it gas a nice idle but when u twist throttle by like 1mm it gets choked and cant go faster than 10 or 15kmh at full throttle. Any help here?
How about cub cadet that is like fuel injected and does not really have the old fashion carburetor . Motor was surging but now it won’t turn on. Any suggestions?
I have a problem with this tool, it's a KTM 250 2T The tool has not been used for almost a year This week I found time to take care of it, I did a fuel-oil change, I cleaned the filter plug, everything, finally I tried to start it, but the car could not start. It only started with carburetor spray and shut off straight away From that I understood that the carburetor needed to be cleaned and that's how I did it. Now the problem is different, the motorcycle drives straight up to very, very high turns I played with the air-fuel screw but unfortunately it didn't help. Is there a situation where the problem is different? Something in the carburetor maybe? need help please
My Kawasaki bayou is revving almost wide open. When I choke... It gets higher. New carb I can't find anywhere that's sucking air in. Any ideas? Please help!!!! Thanks in advance
So I just rebuilt my sons 2005 Honda crf 80f (dirt bike) and it idles good, but when get on the throttle quick it boggs and then when it finally does come up in rpms, when I chop the throttle the rpms come down really slow, not crisp and fast as one would expect. What did I do wrong??
Hi Thomas ,my 250 dirt bike has started acting up, either dies when throttle or when it runs it’s jerking and just nothing happening, any ideas I have cleaned carb and jets with rake cleamer and adjusted float, any help would be appreciated
I have a Yamaha big bear 400 2x4 that missed at anything above 3/4 throttle. It really almost sounds like a governor. I'm thinking maybe the parking brake sensor is acting up? Let me know what you think if you could, thanks.
@@sallycoleman7847 if it's bad it can cause false signals and make it not want to rev but I don't know if that's just for idle or not. I was told that but didn't know for sure.
So I have a carburetor pwk-24 mikuni for a 50cc and when I go to tune it my rpms bounce I've got it some what tuned but still rich in fuel and sooty apart plug I've tryed to change my needle adjustment to lein it out and at that point it don't start I've tryed to adjust my idle screw and it does nothing I can ride it but full throttle it like cuts out and around half I need help please
I have the same carb and Polaris 400L. My problem is that it won’t run with fuel. If I drain carb, it will start and run for 30-40 seconds. As soon as I add fuel it dies. I have cleaned carb extensively but not getting any results. Plug is wet when I pull it out. Thanks for any help!
I’m having issues with a 1998 vn 800 classic. After about 25 miles at highway speeds It’s back fires and dies as of its run out of fuel. I’ve researched this issue and these bikes are known to have issues with the petcock and more specifically the “fuel screen” that sits atop the petcock in the fuel tank, as this is the only filter on the bike. I’ve ordered a replacement petcock because it was the only way to get a new fuel screen. I’m going to replace said parts, as well as add on an inline fuel filter between the petcock and carb, probably only on the “main” fuel line. I’m also going to replace the fuel lines and pull the carb apart so that I may free the jets/floats/needles of any build up, as I know they have not been taken apart in some years. My question to you would be, what else if anything should I look out for and what else may need repair om order to perform properly ?
Hey just a quick question it's pertaining to a honda cruiser cycle. But with the carbs. I rebuilt em changed jets and but didn't change air/mix screws all same number jets just didn't want to clean em. Call me lazy anyway. I get hesitation at the top of all my gears and can't get over 55. Only have about 1/4 maybe less throttle pull in gear with load. Full rev in neutral. Don't really think any pop coming down if I member right. What's my area to reset? Side note. Parts are cheapest off Amazon. Bout the only things I really needed out of it were the two Lil round diaphragms and two o rings for my mixture screws. Should I pull amazon parts and clean oem 30yr jets and put them back in w new Orings and gaskits that I just got? Or do you think since probs at top of every gear and my whole final gear it's my coils and wires?
Hi I have Klx 650 1993 when I’m almost flat at 5th gear it start to cut out and bog soon as u let the throttle off it’s fine but this only happens when I do this ???
2004 ltz 400 revs but seems to stall a bit then regains power sometimes It backfires also took the spark plug out and it’s a cr9 and book says it needs a cr7ei if it’s a ltz400f how do I tell if I have a ltz400 or ltz400f
I have a 2000 Polaris sportsman 400 2 stroke had the atv for about year I drive here and there on a dirt road I live on just recently the bike bike is actually up it will start up just fine no issues there but once I start driving it I could drive it 50 kms and it will work just fine,I just started bogging out and stalling on me I leave it sit for 15 to 20 minutes and starts right up and works fine just wondering if it may need a carburetor clean and new spark plug or new cdi
After changing carburetor and air cleaner filter on my 1996 Polaris sportsman 500, I have a cold natured carburetor but runs great after about three minutes of warm up but every time I go in reverse it conks out. every single time no matter how slowly or how fast you reverse it comes out works great in forward makes no sense. What could be the problem? Mike Griffin Georgia
I have a small mini bike with is 4 speed automatic clutch. Bike cranked over but doesn't start unless I spray gas in carburetor. I took carb off clean it . Still same proablem . Also this carb I cannot take off the lower peace to check float
My Kawasaki bayou 300 has a new carb on it. It starts right up but when I give it any throttle it just dies right away… new to small engines so pretty lost at the moment
I just bought a 1997 formula z Ski-Doo I started up it runs good for 10 seconds and then it starts spitting and sputtering I got a feather the gas and then it backfires and shuts off is that a carburetor problem they need to be cleaned also and it is that the first place I start or should I get new plugs they're pretty new check the gap?? Can you tell me the first thing I do to try to solve this problem

I have a Kawasaki 220 bayou. I put a new carburetor on it, and it starts right up, and will idle, but when I give it gas, it bogs down, and won't go. Could you help me with this problem. Answer me here or make a video. I've tried everything I know to do. Thanks.
Can I just have 10% of your knowledge please 92 dr 350s kick start Runs a little rough, and the whole carb / engine looks a mess, but it runs I am very limited on tools/ mechanical knowledge, but am very afraid to strip this carb and sort it out I have a carb kit for the bike Help !!!! Is this type of carb reasonable simple to work on Any help please 🙏
I just put in a brand new carb on my Yamaha Kodiak 400 and it is spuddering. I did have to slightly increase the idle screw but that’s it. Any thoughts?
On my o7 Yamaha golf cart I pulled the carb to clean it... just regular maintenance now it won’t run without the choke on ive sprayed around the carb for vacuum leaks and it don’t have any the only thing I could not get out was the emulsion tube under or I guess above the main jet
Love the fact you'll make a video for anyone that has a problem with something

Just got a 05 Yamaha bruin 350 in excellent condition. After about two weeks of riding, it started sputtering and bogging out when I give it gas. Took carb apart to clean and it was like brand new inside, but I cleaned anyway and replaced sparkplug. Put carb back on and same problem. If I slowly give it gas it'll slowly pick up rpms and fly but as soon as I decrease gas and begin to increase again I get the same sputtering like it's starving for gas or getting to much. Like I said, this machine hasn't been taken care of very well and has less than 1000 miles. It also will backfire a little bit every once in a while after I get off gas at high speeds. Need help
I have the same condition on a small ct 200
Same problem here on the same quad, did you get it working and what did you do?
Did you ever find out what the problem was
Figure out the problem?
Being a 2 stroke the crankshaft seals may have dried out over time and is coursing an air leak around the crank.
Check all gaskets and crankshaft seals as you don't need to hole a piston with a lean fuel air mixture.
Take care and good luck 👍
Thank you, Thomas. Clear and well explained. My Rancher stumbles , sputters when under load (pushing snow up a hill).
Did you Clean yours like that? Did it work? Mines doing the same thing.
Thank you so much. Wonderful explanation and you helped me fix my Yamaha 350, was running rough and spluttering on high acceleration. Runs like new. Again thank you 🙏
Iva a Kawasaki KLF 300 that won’t start !! It was originally just getting slower and slower to start, so I stripped carb and replaced all needles and jets etc , I found someone before me at left in too many rubber rings and washer on pilot air screw jet , but now after re-assemble it won’t fire at all ?? Just seems to back fire through carb a little bit , I’ve good fuel and I have spark , I’ve tried spraying into carb while cranking to see but still no fire ????
Great content. I have a 82 cb650 cylinder 4 sputters and backfires. I forgot to remove and clean the idle jets. Did everything else.
i have the same issue with my recently purchased kawasaki brute force 750 atv. Seller told me it ran great and had the carb cleaned and re jetted by a local shop just before he put the bike in storage for the winter season. When i showed up to buy it, it spitted and sputtered like crazy and would not stay running. After i rode it around a little bit i raised the choke level up about 15% and it seemed to run fine then...the idle was great and no more sputtering or spitting. Seller was shocked and told me it ran perfectly before he stored it for the winter. I went ahead and bought it anyways knowing it was fixable no matter what and he gave me a killer price on it so I was still stoked to buy it. I so far am just riding it with the choke partially open and it runs fine so far that way at least.
colourtune plugs are handy as you can check the color of the flame which should be Bunsen blue after the choke is pulled in. there is a mixture screw under the carb usually which you can screw out a turn to get more fuel...might be worth a try. As long as the jets are the correct ones and the float heights are correct then with a clean carb the bike should run well.
I love how that’s the first video I watch to learn how to diagnose my issue, and that I feel like it’s solved
Thanks for watching!
This is indeed a brilliant explanation ever to my Yamaha AG 200. By looking at this vedeo I've also checked and cleaned the main horse's nipple from the fuel tank to the cab which was being blocked by so many dirts. 2 Problems that were solved are engine dies when at low RPM or when at higher RPM, and hard starts again at about 3 minutes. ❤❤
That's a man who knows what he's saying. Thank you
Thank you!
Having a heck of a time with my 125cc sputtering and definitely not idling.
Always has run great previously.
I cleaned out the carb but will re-check these side ports.
I’ll let you know if it works!
This was probrably one of the best videos about small carbs thank you so much I dont think Anyone could have explained that any better video was straight to the point.. Ive been struggling with a small carb. First it was leaking out the over flow then it was backfiring thru the air intake now its bogging down with throttle doesnt die starts right up but bogs way down driving me crazy but im pretty sure after dozens of videos this is the video i needed to see. Will let you know thanks again
im going to try this today. i have an old 1991 honda 300 fourtrax that seems to carbon plugs almost instantly. the bike idles great and can putt around in SL no problem, but as soon as your on the throttle to get through your gears, its as if the mid range power is completely gone it struggles to accelerate, and it starts to come back in to normal in the high end RPM. its causing jerky acceleration through gears and when finding your cruising speed. ive taken apart the carb and cleaned the jets, along with replaced the air and oil filters, plug and oil. somewhat fixes the problem but reverts back (my guess once the plug fouls) im starting to think the float may need to be adjusted now, thanks for the new lead!
Man runs perfect in every gear when you put it in reverse it don't have no power it just spits and sputters will not go backwards I also bought a brand spanking new carburetor and put it on it and it run perfect but like I said when you put it in reverse it just spits its better it won't go backwards unless you're on flat ground
Thank you!!! I am a complete noob and just started getting into ATV’s last summer. I am currently on my pulling carb for the 7/8 time done yesterday. the same carburetor in and out with out luck
This video may be my saving grace
What kind of atv are you working on? And did you try this yet? Having problems with a 2004 predator 500 stalls at idle. I’m going to try and pull the carburetor this weekend.
i don't think i've ever seen a pair of old school man hands like this in about 20 years. cuddos to you sir you use the body god gave ya.
Best explanation yet. 2 out of four are doing this. I'm on it. Thanks. The 99 honda 300, never a problem. The rubicon 472, both have this issue. Was puzzling. Will follow.
I have a 2004 Can-Am we had to clean the gas tank and all that out. I was having trouble with the original carburetor. We think we cleaned it out properly but would not work. It was getting too much gas so I bought a Chinese carburetter and it’s still doing the same but running, a whole lot better but still not not running right should I just buy? Another Chinese carburetter Maybe I got junk one PM me if you can
I have a situation that's very confusing, I took a ride into a patch of woods on my 2017 Polaris 450 HO for maybe thirty minutes-there was no path so I was running over trees big and small-I made it out of the woods but at the treeline, my engine started running rough, sputtering, backfiring. Luckily, I made it back home at a crawl while cranking the throttle back and forth, I had a new plug -OEM- so I switched it out- never did see the carb to see if I pulled anything loose, the plug didn't help much. I lifted the front end up so I could check out the bottom side, saw nothing pulled loose or hanging. That's my situation and any help would be appreciated
Question, I just bought a 1994 Kawasaki Bayou 220 and the starter sounds horrible. I replace the starter with a brand new one off of Amazon and the starter sounds exactly the same and it’s almost like a grinding sputtering noise and it sounds like the starters not getting enough power to crank the four wheeler. Any ideas?
Hi . Thomas thank you for the info, i have an issue with 2006 ktm 50sx with stock carb and jet Dellorto carb brand. cleaned carb. as you said. 4,x. it boggs down at full throttle bike on stand. 60/1 fuel ratio. im in california 40 miinutes inland from beack. so u get idea on elevation. i appreciate ur help
That’s crazy I was looking at buying a 2008Q link 700 front runner side-by-side with a sputtering issue in the first video. I find covers my ATVs issues I have a 400 Polaris and I’ve been struggling with the sputtering issue so now that took care of that problem.
How do you get the Main jet tube out or imultion tube that is the needle goes in & out of.. thank u.
I have a 1976 Sachs engine, Sparta buddy moped, 49cc. I pulled the old carb apart and the slide was ready to breath in half. I got a new keign carb and installed it. The moped starts fine, pulls hard, but breaks up at full throttle? Any suggestions...
Thank you.
I have a Farmall 100 tractor that fires up with no problem. Then it starts sputtering and puffing smoke out the exhaust like it's flooding or choking. After doing this for several minutes, the engine will finally die. But, I can pull the starter and it will immediately fire back up with no hesitation before repeating the same issues as before. When it is sputtering, the rod leading from the carburetor will move back and forth instead of staying stationary like you would expect. Do you have any ideas as to what may be the cause of my issues? I inherited the tractor from my late grandfather and have some mechanical experience, but am in no way a professional. Any advice you could provide would be greatly appreciated!
Problem now
Harley carb shoot fuel mist out the carb mouth when throttle is wacked. Jetting? Or something else. ???
I have a 2001 Yamaha Kodiak that starts up fine and runs but if I let it idle after a few minutes it will stall. If I put the choke on just a little it runs fine. It also will pop or backfire a little if I rev it. Ty
I've got a 1962 Ford 3000 tractor with a Holley R3655A carb. I have removed it and am in the process of cleaning and installing a kit. However I can not get the plunger to come out of the little tower it is in. I've had it soaking in carb cleaner for days and it will not pull out. Do you have any tricks for that before I attempt to drill it out?
It felt like a buddy was helping me understand carbs better. Thank you.
Thank you for watching! Happy to hear!
I have a 98 yz250 2 stroke. Previous owner must have hit something very hard because the front rim was so bent that when moving it, the tire would rub the front shocks. I'm having a similar issue. But mine is occurring as I'm hitting the powerband. The bike will act like it's starving for fuel and after a few quick twists of the throttle it'll go back to full power - resulting in the front wheel coming off the ground. I'm going to pull the carb off this weekend and give it a good cleaning. Fingers crossed that I find some green goo. Otherwise I might be looking towards checking out the power valve. I'm new to 2 stroke dirt bikes/ bikes in general. I purchased it 2 months ago and have slowly been replacing parts. I'm a diesel mechanic and love tinkering with small engines. I'm open to any suggestions.
Is it normal for the carb floats to be stuck in the bowl? Is this the design? Never seen that before. I have a 1982 yz125j that keeps flooding the cylinder and plug. Can you make a video on that cause and fix?
Great video. I succeeded in rebuilding both carbs on my 1997 Polaris 500 snowmobile thanks to this video. Reassembled carbs on machine and fired it up. The mag cylinder is not drawing in the fuel, thus the mag cylinder is not firing. Suggestions?
In the bowl, should the idle jet be below the fuel level....in the fuel.
No float level specs,
No name carb.
Not a single marking on carb.
Thanks in advance
Thanks man. Just bought my first carberated bike and want to learn as much as i can about it so i can wrench on it myself. It spits occasionally, its about 40 degrees out here in colorado, and it apears to only do it when choke is all the way in... so it may just need to be dyno tuned... apparently again... not sure if its tuned for this elevation. Assumed it was and that may be a mistake as i should have asked and the dealership may have shipped it up from elsewhere.
Hey man. Love your video my mate has 150cc pitbike. He had no air filter. I make him get air filter. Bike runs bad with air filter. We clean side of jets and all carb. Bike still runs OK when take off air filter. I have try to adjust air fuel mix screw but it is always lumpy in the top end and try’s stalling
Is not likely I personally will attempt this, but you are a great instructor!
Clear, concise explanation. Thank you for the insight.
Well done 👍
But please my I say something
Carburetors, engines do not suck air or fuel.
Atmospheric pressure does the work, ie at sea level it is
1 bar = 14.7 LBS =Atmospheric pressure.
I understand it's easier to explain that an engine sucks but it is Atmospheric pressure that pushes the air into the carburetor and fuel into the conbustion chamber as the piston goes down the stroke.
Anyway I am positive that you have helped many a person 👍👍
I have a taotao 125cc Dirtbike. The carb it doesn’t run great with unless it’s in higher rpm. Whenever it is idling I have to feather the throttle to build the rpm before going. If I just hit the throttle from idle it bogs down and dies. It’s super annoying to ride because of this. Also the piston was on wrong with the intake and exhaust sides flipped since I fixed that it does run better but still is the same bogging problem. I’ve adjusted the carb so many times but to adjust the air fuel screw I have to take it off and it’s annoying taking off over and over
My gas golf cart only wants to run when the choke is pulled out. What can I do to fix this. Thanks for your help.
This is the pilot jet in the carb bowl. Remove clean and replace.
Question for, Im helping a friend with a polaris 500 predator carburetor issue, the initial complaint was only start and run on choke, would not accelerate but stumble flat out upon trying to increase rpm. He brought the carburetor to me, I opened it up found a plugged main jet and slightly plugged pilot jet / emulsion tube, all clean now and reinstalled, now it will start on choke and idle off of choke but as soon as you try to accelerate it stumbles flat , the diaphragm slide does move up but kind of bounces as it stumbles to rev up... What is going on here, no vacuum leaks on the intake boot either...
I have a skidoo that dumps fuel out the side tubes on the one side but how do you take the plastic pieces out of the side i broke one of the hose fittings off its all plastic one on each side
I've done all that can you let me know we're my mixture needle needs to be? The carb needle fell and I put the e clip on but can't find the right mixture with the neddle
Ive got a generac 3100 pressure washers runs great carb cover off . put the cover on spitts and shutters,
Like the video and so correct, I have a polaris Razor that was cleaned and I took the entire thing apart. I started the engine and adjusted the air fuel screw along with the idle screw. The engine idles but will not accelerate without popping and spitting. I have adjusted the needle through every setting, please help
How do you diagnosis Hanging idle on deceleration on a 400cc 2stroke ?
I have a 04 kfx 50 quad I just got done cleaning it all out had a lot of build up in the carb white residue . I put it all back together but it just doesn’t throttle up quick almost like bogging out and not reaching full throttle what could it be
Thanks for the info… I have a riding mower that the carburetor is spitting out gas & I believe oil/ it’s some type of black liquid…. Any thoughts?
I have a 1997 Honda shadow 600 I am a new rider and don’t know much about bikes yet. Bike starts up fine and runs well up until 40mph then it starts to sputter and not accelerate past 50mph, the bike struggles to go any faster. I put sea foam in about 3 days ago, 50 miles and it still does the same thing.

Me and my dad are working on a clients Yamaha TT-r230. He had let it sit for number of years. We had put a lot of new parts on it and still can’t get low rpm’s. Starts and idles perfect and all the power at top end. Just no low end power just stutters and wants to stall. We flushed the tank servile times. We all so put a new pepcock, fuel line, carburetor and battery on it. We have tried tuning the low end jet and nothing makes a difference but if we pull the choke 1/8 the way out. It will run like a dream. Can any one help us and shed some light for us please? Thank your guys.
i have a 32mm cvk carb. idles great. once i crack throttle, no power and just popping. carb is clean. what would u suggest. bike is a 232cc 2 valve powered taida gy6. if that matters. 600 above sea lv
Got a pwk 21mm carb on qmb39 with 47mm piston. It bogs unless rpm is up.

I have a 2008 Polaris Rubicon ATV, is this the problem with it sputtering when the gas is depressed
I have a 125cc venom quad brand new .Have problem starting I use choke when cold it takes a few cranks starts but if touch throttle it quits and I notice fuel coming up in the cap hose .I set the air fuel at 2 turns and do the idle screw and some times it allows throttle but most times not as I say brand new quad.?
I could not figure it out. My new motorcycle only has 200 miles on it. Came with a carburetor I have to work to get the screws off the bowl. No biggie. Yet it puzzled my on what it was doing. Did not make sense. Now it does. So, I'm going to do exactly what you suggest. I will see. If works, you just saved me money and a big headache. Thanks for your help.
Thanks for "very well explained" instructions for repairing an engine that only runs on 1/2 choke.
Makes perfect sense. But why would my gy6 motor be running very hot. After a needle cleaning in the carb and valve adjustment? Please help me. I can't afford to have my engine seize!🙏🙏 i need it for work!!please help me out???!!🙏🙏🙏🙏
I'm having this problem, but it's a new carburetor, it was my first motor kit and I bought a zeda 80 when it was in stock, so I started a bike build for my son with my first motor similar to the PK 80 on a occ chopper bike everything is offset to the left cause of the wide bike tire, well my issue doesn't seem to be the carburetor, and being that the exhaust system is a flex tube pipe could that be a problem why it spitting and sputtering.
I have a KTM 2017 xc300 i cleaned my carb but it hadn't stop spluttering idk what else can I do. I'm going to chek the float needle. I already cleaned the jets and also the idle jet. I completely removed them and poke them like you did in the video. Please help
I have a 2008 Suzuki DRZ 125 and I can usually kick it over. Though when I turn the throttle it does not return to idle but it keeps going up or staying if what you just turned the throttle could you help me of what is going on?
Mxz 700 2001 starts n runs good and all of sudden it starts backfiring, changed choke lines, cleaned the carb too, just wondering if the choke has something to do with it, starts backfiring like crazy!
I have an old motorhome. It is back firing through the carb. Flames go everywhere. A good friend of mine got burnt badly when the same thing happened to him while working on his motorhome. I want to get the motorhome fired up. Usually requires a squirt of starter fluid and a bottle and hose with some gas in it to keep it going. Any way to keep the back fire 🔥 from catching me or the motorhome on fire?
Have 2003 artic cat ATV put new carburetor in idles fine when go to accelerate just sputters no power ...any thoughts what could be the problem?
Hi Thomas, I have some questions I'd like an answer for. I have 1995 summit 670 with vm40 mikuni carb, everything is squeaky clean almost spotless in there everything new except for needle jet and needle. (needle valve, seat, main jet pilot jet, gaskets) and had it set up to factory such as round slide opening air screw and idle screw float arm adjusted to 19.6mm bottom of the arm to face of carb where gasket sits.
carb was keep flooding I tried to have float arm to 20.5mm didn'tdo it. flipped the arm set it to the height still flooding. I took the slide out and excessive amount of fuel was coming out from main jet( throat I think), thru jet needle tube. I blocked the jet with needle and tried again and breather hole and such was puking out fuel. why would it be keep flooding? and its happening to both of carb and I dont know if floats will go out at same time
You make a whole lotta sense bro! I'm having the same sputtering symptoms, only I have a Harley 2009 cvo fatbob with electronic fuel injection and what you just explained with the example with a carburetor is the same in nature, "Thanks big guy and be safe!
got a 2007 polaris atv 500 efi. starts but bogs when adding throttle. replaced fuel pump, fuel strainer, injectors, everything fuel related all the way. no change, when i put my hand over the carb, air intake it seems to rev up fine. any ideas?
Polaris 400 2 stroke I put new carb on it want idle and wants to bog down when driving at full throttle I have leaned and richen the carburetor nothing has changed. Can you please help?
Helloe Thomas. got a Raptor 350. (little story) bought it in bad shape. but it started and idled perfectly but i couldnt rev it (died) found the choke was corroded stuck so i got it loose and changed the sparkplug. wouldnt start. cleaned the carb, now it backfires ALOT(when revving too). it wont idle nice, either i rev it to keep it running or use the choke so i idles high. and it pops through the intake now. seems like everything became a mess with it. do you know what could be wrong here?
my friend bought suzuki an125, it is 4t but with 2t carb. We cleaned it very well every part and every hole but that damn carb sucks so much fuel and it needs so much air at that level we should not put air filter. One more the problem is it gas a nice idle but when u twist throttle by like 1mm it gets choked and cant go faster than 10 or 15kmh at full throttle. Any help here?
How about cub cadet that is like fuel injected and does not really have the old fashion carburetor . Motor was surging but now it won’t turn on. Any suggestions?
I have a problem with this tool, it's a KTM 250 2T
The tool has not been used for almost a year
This week I found time to take care of it, I did a fuel-oil change, I cleaned the filter plug, everything, finally I tried to start it, but the car could not start.
It only started with carburetor spray and shut off straight away
From that I understood that the carburetor needed to be cleaned and that's how I did it.
Now the problem is different, the motorcycle drives straight up to very, very high turns
I played with the air-fuel screw but unfortunately it didn't help.
Is there a situation where the problem is different? Something in the carburetor maybe? need help please
What if I do clean the sides and everywhere else but I still have a 1/4 throttle stumble/sputter
Why would my 1983 Suzuki 125 quad It runs and idles and revs if you feather the throttle

When I choke... It gets higher.
New carb
I can't find anywhere that's sucking air in.
Any ideas?
Please help!!!!
Thanks in advance
So I just rebuilt my sons 2005 Honda crf 80f (dirt bike) and it idles good, but when get on the throttle quick it boggs and then when it finally does come up in rpms, when I chop the throttle the rpms come down really slow, not crisp and fast as one would expect. What did I do wrong??
Hi Thomas ,my 250 dirt bike has started acting up, either dies when throttle or when it runs it’s jerking and just nothing happening, any ideas I have cleaned carb and jets with rake cleamer and adjusted float, any help would be appreciated
My new carb for 125cc two stroke is running too rich even on 1'1/2 air setting, sputtering while riding, should I adjust the needle setting?.
I have a Yamaha big bear 400 2x4 that missed at anything above 3/4 throttle. It really almost sounds like a governor. I'm thinking maybe the parking brake sensor is acting up? Let me know what you think if you could, thanks.
how does the parking brake sensor make it act up ?
@@sallycoleman7847 if it's bad it can cause false signals and make it not want to rev but I don't know if that's just for idle or not. I was told that but didn't know for sure.

I have the same carb and Polaris 400L. My problem is that it won’t run with fuel. If I drain carb, it will start and run for 30-40 seconds. As soon as I add fuel it dies. I have cleaned carb extensively but not getting any results. Plug is wet when I pull it out. Thanks for any help!
I’m having issues with a 1998 vn 800 classic. After about 25 miles at highway speeds It’s back fires and dies as of its run out of fuel. I’ve researched this issue and these bikes are known to have issues with the petcock and more specifically the “fuel screen” that sits atop the petcock in the fuel tank, as this is the only filter on the bike. I’ve ordered a replacement petcock because it was the only way to get a new fuel screen. I’m going to replace said parts, as well as add on an inline fuel filter between the petcock and carb, probably only on the “main” fuel line. I’m also going to replace the fuel lines and pull the carb apart so that I may free the jets/floats/needles of any build up, as I know they have not been taken apart in some years. My question to you would be, what else if anything should I look out for and what else may need repair om order to perform properly ?
Hey just a quick question it's pertaining to a honda cruiser cycle. But with the carbs. I rebuilt em changed jets and but didn't change air/mix screws all same number jets just didn't want to clean em. Call me lazy anyway. I get hesitation at the top of all my gears and can't get over 55. Only have about 1/4 maybe less throttle pull in gear with load. Full rev in neutral. Don't really think any pop coming down if I member right. What's my area to reset? Side note.
Parts are cheapest off Amazon. Bout the only things I really needed out of it were the two Lil round diaphragms and two o rings for my mixture screws. Should I pull amazon parts and clean oem 30yr jets and put them back in w new Orings and gaskits that I just got? Or do you think since probs at top of every gear and my whole final gear it's my coils and wires?
Hi I have Klx 650 1993 when I’m almost flat at 5th gear it start to cut out and bog soon as u let the throttle off it’s fine but this only happens when I do this ???

On my o7 Yamaha golf cart I pulled the carb to clean it... just regular maintenance now it won’t run without the choke on ive sprayed around the carb for vacuum leaks and it don’t have any the only thing I could not get out was the emulsion tube under or I guess above the main jet
