Coleman mini bike not starting/only running with choke? here's something to check.

Today we have a Coleman CT200U-EX mini bike that does not want to start up at all. Pulled the carburetor off and gave it a nice cleaning, put it all back together and it fired right up! hopefully if your bike isn't starting up or only running with the choke this works for you. Thanks for watching!

[@thelaymanlife8591]

So guys, update on the coleman mini bike, me and my friend both owned one and removed the governor out of both. A couple months with riding it like that they both seemed to stop working. I believe the higher rpms caused the engine to lose compression which caused it to stop running right. I've heard some people say it's better to buy the predator engine because it can handle the higher rpms better.

[@Deucealive75]

What some people say is just speculation. If you abuse any engine it's going to break or wear out much sooner than it should. The Predator isn't some magical all powerful unbreakable engine that some make it out to be. I will never get a Predator 212. There's just too many better options out there including the new Pred 224.

[@drittgaming2350]

Going to upgrade mine and pulling the governor is one thing I plan on doing what you can do to counter the high RPMs is to put stiffer valve springs in it. Could have burnt up the motor maybe another issue or your piston and your valves may have been playing a little bit of patty cake. Either way these motors are cheap and a dime a dozen and there are parts a plenty so I'm going to do all kinds of stuff to mine and see what I can get out of it. Also if you want to get a little bit more speed out of it I heard the belt drive is a good replacement for the clutch. So many options lol

[@drittgaming2350]

And have you checked the spark plug?

[@AsTheWheelsTurn]

yeah I think it burns the valves when you run too high RPM on them. personally I dont care to go faster than the 20 mph they do stock because they have no suspension and are not very stable at higher speeds , if I want to go fast I would just get a real dirt bike, these little bikes are fun for around campsites and putting around in the neighborhood.

[@logandardinski3345]

I know It might not seem like it’s doing a lot when you’re taking it apart and cleaning it but i assure you it’s doing more than you think I just did the same exact thing to mine and it started right up on the first pull

[@thelaymanlife8591]

Glad to hear that bro!!!

[@heathercahill740]

Thank you it works

[@AsTheWheelsTurn]

this world like a charm for me! I was sure it was going to need more than just this because it was running so badly but it was just a clogged jet in the carburetor. using compressed air along with carb cleaner and just spending 10 minutes spraying and blowing will result in a perfect running machine again. and if not just buy another carb they are cheap.

[@thelaymanlife8591]

Yea, the carbs they have on Amazon are crazy cheap! I'm an impatient person, tho so when I want to ride it, I want to ride it right then. I'm glad I was able to help!

[@JerrySmith-bp1it]

I had the same problem. Found the carburetor loose. Went to tighten up the bolts a little and found that the boats were stripped out now I'm having trouble finding the studs. Anyone know where I can order them?

[@817x34]

Mines have a intake but idk… same problem… Wheels get stuck when it doesnt work too

[@weenfain2321]

I’m currently having an issue with mine. Yesterday wouldn’t run without the choke. Cleaned the carb today wouldn’t go at all with the choke on and kept dying when I turn it off. Have tried everything.

[@thelaymanlife8591]

Hey man, I would make sure you're getting enough fuel and spark. To troubleshoot and see if you are getting spark, pull of the air filter and spray carb cleaner down into the engine. Leave the choke off and try to crank it over. If it starts up its still a fuel problem. Keep trouble shooting and let me know what you get.

[@lakeifjohnson7143]

Did you fix it

[@Bobschanel.]

Mines has a different carb but I’ll try it and let you guys know if it works

[@exversee5891]

Hey man I removed my governor 3 days ago and the bike would start but every time I gave it throttle it died. I gave it some engine starter and it worked but now the bike doesn’t even idle and the new Coleman carbs don’t have an idle screw. I’ve looked everywhere and I have no clue what the problem could be.

[@thelaymanlife8591]

Removing the governor on those is tricky. You need to put a spring to make sure it drops back to idle. I have a video on doing the governor.

[@AnthonyRobles-xk4vf]

Why does my bike drives off when I started?

[@ClipCraze212]

Any ideas for mine? Doesn’t start, put new oil, gas, and carb in it. Oil leaks through exhaust pipe.

[@AsTheWheelsTurn]

if you have oil leaking thru your exaust pipe then it may be that it sat on its side by accident , if you lay these on their sides and leave them that way oil runs into the combustion chamber and then they will not run, I had it happen before where it was so full of oil in the cylinder I couldn't even pull the pull cord and turn the engine over. best thing to do for this is take the spark plug out and use a shop vac to suck the oil out of there, once you can get it started it will smoke real bad for a while as it burns off the oil that go in where it shouldn't have. if it is not from laying it on its side and you have oil coming out your exhaust then the other thing that could be wrong is a cracked engine block or bad seals, if that is the case you may as well just get a new engine for it, they are not very expensive and the old one can be used still for parts.

[@troyholland3436]

I’m having a random Throddle issue on my ct200u engine is brand new the Throddle just worked perfect a couple days ago it’ll twist but will get stuck a little and not return great everything is hooked up correctly

[@thelaymanlife8591]

Those springs that they have for the return aren't very well made. I would take a look at that and maybe see if you need to clean it off or replace it.

[@stgonzales]

Any ideas for mine? Starts with choke, take off choke and stays on, when I try to run, bugs out and hard to restart. Gas is fresh, even changed the carb. Anything will help. Thanks

[@thelaymanlife8591]

Make sure it's got good spark. And check and make sure you've got good gas flow going to the carb

[@dallias347]

Mine starts but it’s turns off automatically and I can go with my choke on but once I stop pulling the throttle it turns off, I cleaned my carb and everything, but it’s still not running, can you help?

[@thelaymanlife8591]

Hey man, I would double check the carb. Those things have small jets in it that can get dirt or anything like that stuck in it and that'll be enough to cause it to run rough. I would also check the spark plug to see if its loose which would cause it to not have enough compression also check if the plug is creating a good spark. If none of that works check the fuel lines and see if its clogged.

[@RicketyRocket]

Sounds like you need to turn your idle screw in a bit to the right.

[@brzdy81]

Hey Boboos I would take a look at some of the comments. Someone had mentioned a gas cap can also cause it to not run right!

[@ge0ne063]

Same here Boboos....did u ever get it running ?

[@atronwardiv1307]

3:26 when you said that you blew the jets out did you take them out or did you leave them in and air compress it

[@thelaymanlife8591]

If you really wanna clean it you can pull them out and clean them using a small flat head. I normally just blow some air into the carb depending on how bad it is.

[@deegaw11]

Hey I recently purchased one and it’ll only run if the throttle is on. If I don’t give any throttle it’ll shut off. Also it will only idle in choke. Do you know what I should check? Thanks in advance.

Thats normal just dont keep it on its side too much because the oil will leak out the carb and that white smoke is the oil getting burnt up
