Coleman CT200U Mini Bike Carburetor removal and cleaning

[@josemares1439]

For those that can't remove the main jet due to the 1 way screw head get you a 1/8" flat head screwdriver place it on the jet then whack it a few times with a hammer and the driver will be forced into the jet since it's soft brass then just unscrew it and the jet IS still useable

[@dannywayne3109]

Awesome video! It's still useful 6 years later. Thank You

[@frogman4201]

This is really helpful but is there a way to stop gas from coming out of the engine I literally got it all over my clothes

[@esaabdullah2762]

Drain gas first

[@FilmSteve]

Remove the clamp off the fuel line, remove the fuel line with needle nose pliers but do not release. Get a stubby Phillips screwdriver and plug the hole before releasing your pliers. Repeat in reverse to assemble

[@FatMajorKoob]

I just stuck a bolt in it

[@davidmauricio7406]

Turn the gas off

[@michaelbriggs6028]

Remove the gas tank

[@DeadBaron]

Should have had a warning to clamp off that fuel hose lol. The shutoff is in the carb, so removing the carb will let it all spill out.

[@lilswampy9402]

Dead Baron yep I just lost a tank of gas

[@danielmoreno7056]

Thanks for the warning lol

[@cannamink]

I saw your warning and still got gas everywhere 😂😂😂

[@MrManVR179]

What size flathead to remove the jet that is inside of the bulb?

[@lazzer408]

You forgot the idle jet! Remove the idle adjustment screw to access the jet. Pull the jet straight up. Drill the cap covering the adjustment needle. Remove the needle. NOW you can clean the body of the carb, clean the jets, then reassemble.

[@Sp3cial3d3st]

That last bolt you move before the carburetor was not even necessary and carburetor cleaner is not the best choice cuz it leaves residue and what you want to use is brake cleaner is Best Choice out there does not hurt Parts at all and I'm a certified technician but good video

[@Sp3cial3d3st]

@JIMMY HENDERSON GOD BLESS YOU

[@luh_tunka]

when my bike was new it was necessary now its sort of worn out so not anymore but yes at first its necessary.

[@AManOnline.]

Would doing this fix a backfiring issue?

[@johnmartin5153]

Is this the same carb that’s on the bt200x ?

[@81MrKMan]

I have two that I just bought new but were manufactured in 2018. On one it backfired when turning off and the top little black plastic, I assume air inlet, thing on top with a 44 printed on it popped out onto the floor. It looked like it might have been glued in where this carb in the video has a black perpendicular screw holding it in. However on my other one with the part still attached there is no black plastic screw. Not sure what to do.

[@BIGDADDY19633]

Is it me or do you just see alot of videos of people fixing coleman200. And not that many of riding them

[@WoLFSkYBLuE69]

Never had a problem with mine after five or six years dude.

[@autobotsvsdecepticons9165]

Well made instructional video, thank you!

[@masonneubauer3874]

I cant wait till mine comes

[@djderay949]

i just had bought my minibike about a month ago and added the gopowersports kit on it excepp the larger fuel jet, and afterwards my engine started bogging down pretty bad at a higher idle, i take off my carb cap and put my screw head into my jet but decided i was going to wait, maybe i got some dirt in it or something? please give me your opinion. my bike has lost a good amount of speed and its kinda lame, but she does sound and look sweet. any info will help, thanks.

[@ilovecheesecake516]

did you figure it out? mine is doing the same thing

[@imfine.4915]

Instead of the airlifter can I use a header exhaust pipe?

[@denykonecny8157]

Hey Paul. Really helpful video. I was exactly what I needed to know. I had a plugged jet screw which I assumed was the culprit. I followed the steps to the letter and it started on the first pull after putting everything back together with the choke closed. It was very rough on idle and would not rev any higher. I played with the choke while it was running and it seemed to fix the problem and I was able to ride my mini bike for the first ( new build from scratch) around the yard. I did notice that the air filter assembly had a crack in it (approximately where the stickers are on the front). Could that be the problem with it still running rough with the choke off? All my linkages and springs are ll in place and functioning properly. What am I missing?

[@kingstonlabelle6954]

Same for ct200u-ex?

[@markstewartallen]

Paul, I have a new 200T mini bike, running at about 5500'. It started with first pull and choke on, started to warm up and then after about 2 minutes it would get really choppy idle, but if I take the choke off, motor dies. Tried modest adjustment to idle speed screw, but to no avail... not sure what you would recommend, and also, what is the factory spec for idle screw setting? Screw in all the way and then back out 1 1/2 turns? Suggestions welcome.

[@Deucealive75]

If it idles choked but stalls with the choke off it is not getting enough fuel to stay running. If I were you I would start with what you see in this video. Be very careful with the carb gaskets and how they go on. If you still have the issue after that you should scream at Coleman and hope they send you a new carb or provide a solution. I had a carb issue on a new harbor freight engine that I couldn't get rid of and they actually sent me a new carb that took care of the problem. I like tinkering with this kind of stuff. If I had your problem I would buy a tiny drill bit set and open up the main and idle jets one size at a time until there was enough fuel to idle, then go from there. The idle jet is not pulled and cleaned in this video. These engines are set up to run as lean as possible to save fuel and meet EPA regs. The only way to adjust things is by messing with the jetting. I wonder if part of your issue is the elevation you are running at? I know they actually have high elevation kits for small generator engines similar to the engine on your mini bike. Those kits probably have different jets for the carb. Good luck with your bike.

[@GBsPitstop]

I have bought a coleman mini bike and a Coleman 2 seater kart and both are doing what you said. they will start right up with choke on then moving choke off slightly will die. I let my son ride the kart with him giving it gas to get took off and noticed the exhaust was bright red under shield. it has to be lean. so i plan to remove both carbs and clean them although they are brand new and i should not have to do this. after that if they are still lean will figure how next step to richen them a bit. i took the carb bowl off the kart and it had some sediment in the bottom of the bowl. its had less than a tank ran through it and i know my gas can was clean so wondering it this is residual from manufacturing.

[@shootinnscootin5545]

What size jet should I upgrade to if I add a new exhaust?

[@ccascio777]

do you know how to take the fuel jet out

[@anthonyderose6069]

Thanks for the video

[@Zenko96.]

My mini bike will turn off after staying on for a couple of seconds when I turn off the clutch but if I accelerate it it won’t turn off, it only turns off when I don’t I already did an oil change

[@Plane-tw9xz]

Gotta clean the carb maybe new spark Plugs

[@bryantbaskerville5166]

Thanks a lot. My bilk wouldn’t start until I watched this video 👍🏾

[@Bret4207]

I believe that's the EPA "California" carb. You can get a $15.00 replacement carb that has the removable jet and low speed (I think) carb adjustment off Ebay.

[@raptorgames9]

My coleman has recently started jerking and jumping when I accelerate. I can't ride it like this because it's unsafe. I cleaned the carb, changed out the spark plug, and gave it fresh gas. It still does it. I'm running out of ideas of how to fix this? Any suggestions? Anyone with the same problem?

[@ColeDuarte-tl9jl]

Change the oil

[@ashtonjayden5886]

It could be your clutch going bad

[@WoLFSkYBLuE69]

Likely the clutch

[@rebob1892]

You need a clutch, easy fix & doesn't cost a lot of money. Lots of vids out there with tips & tricks.

[@iiamareii2789]

Mine does the same thing its been a year since you commented this but did you ever fix your bike? Sounds like we have the same problem

[@kerrygatling663]

Have ever dealt with a one-way jet? (It has no reverse grove cut into the jet) so it only screws in.

[@LokaNator]

Mine the same way

[@josemares1439]

Get a 1/8" flat head screwdriver... about 6" long and stick it into the jet and crack it with a hammer a few times and it force itself into the jet then just back it out

[@skillchamp4208]

How often should I clean it?

[@creepersdungeon4870]

From what someone told me every 6 months that's what I been doing and has been going well 🤷

[@ThatJerkFromCali]

Why doesn't my either of my carbs on my ct200u's have an emulsion tube?

[@daddingaverage7095]

Can you make an updated video for the ck100 go carts? No help on Coleman website. Really outdated and/or underdeveloped.

[@Couch71R]

When I turn on the fuel it pours from the back side of the bowl. Maybe needs a gasket?

[@FatMajorKoob]

Make sure the gasket it sitting right

[@outon2s]

Thank You!

[@trippyfierce9759]

I have the same mini bike and when I start it, it runs for a few seconds and then died especially if I hit the throttle it will kinda go and then die I’m guessing it’s the carburetor because iv been running it without the filter any ideas?

[@GoHomeKamala]

Mine does too. Put another plug in then it starts then doesn't die but hasn't any power to even move the frame. Have also drained the stale gas but I can only believe it's the carburetor.

[@Carvman]

Check your gas line

[@tomjankovsky1832]

Beware...gas will pour out everywhere if the tank is full. Get a bowl/can ready or empty the tank first. Also, my main jet had a one way thread so it could not be removed. Back flowing all ports worked fine though. My engine would start fine but die if I turned off the choke. Perfect now...thanks!

[@pineconeenthusiast5541]

How do you unscrew the jet screw

[@jaredi3810]

I couldn’t unscrew mine. I think the new Colemans come with a jet that has a jet designed to be screwed in and NOT screwed out... bullshit

[@pineconeenthusiast5541]

Jared I yeah that’s pretty awful design, I’m thinking of replacing the carb anyway. I’ve had some problems with the throttle.

[@natesmino]

The jet screw appears to have a one-way screw head so I cannot remove. Any advice?

[@ronaldledet1443]

Yes why do them Idiots make a Jet Screw like that -- just causes lots of Head Aches. And the person you sell it to later complains that you messed up the Carburetor thinking you took it apart and stripped out the Jet Head.

[@raptorgames9]

My coleman bike starts but jumps and jerks while riding. Sometimes it just shuts off. It's unsafe to ride it with the jerking. I cleaned the carb and changed the spark plug, but it still does it, any ideas?

[@bush5389]

@@raptorgames9 Most likely the clutch

[@ilovecheesecake516]

i put the stage one kit on mine and i was trying to take out the jet and i realized it was non removable. Now it doesn’t idle well and bogs down at higher speeds. Any advice? I saw one channel screw into the jet to remove it.

[@josemares1439]

Put a small flat head screwdriver that'll fit inside where the jet is and give it a few cracks with a hammer and back it out easily

[@kingmatthews5436]

thank you so much it helped a lot!!

[@lilswampy9402]

Do all Coleman mini bikes have the same carburetor?

[@lilmeatevan]

Pretty much depending on size of your motor if you have the 200cc then yes and pretty much Every other 212 cc size motors will be the same

[@VirginiaTombstoneRevival]

Should there be any fluid inside of he float? My mini bike is leaking fuel from the back of the carburetor and I can’t figure out how to fix it to save my life.

[@jameslesesne7969]

Christopher Kirby if there’s gas inside the plastic float that’s not good. It means you have a crack in it somewhere and it’s filling with gas. Which in turn will cause it to not shut off the gas when the bowl is full. Also check your gaskets.

The only mistake you made was you put float Bowl on oriented wrong. It has to be oriented so the pin can't come out of the needle and seat.
