clone problems

[jetlag]

My friend has a 09' Blue clone in his kart.

It has the governor removed and a header.


Sometimes it has trouble starting/idling. As long as he has the gas wide open, it runs like normal. But as soon as he takes his foot off the gas and slows down, it will start to stutter, hunt for idle, then die. We've adjust the idle back and forth but that doesn't help.

I opened up the carb and checked it, clean. Spark plug was clean.


Sometimes it starts up fine, he can drive around for awhile and then it will randomly die. If he tries to start it again, it won't. We took a break after riding and it died, maybe 10 minutes. It started right up.


Any suggestions? Ideas? Advice?

Hum...I think those emissions carbs can have the plastic caps off and be tuned...not sure. Davidsfarm said something about it.

All you have to do is to tear the crap out of the plastic caps on the needles so they come off and then your good to go.

What are you talking about?

It sounds like a lean idle condition. Because of your supa mods you need a lil more fuel.

If that was true, then it would do it all of the time. Not randomly.

Well clean your carb.

bout the plastic caped emission carb?

Hum...now that I read it. Try starting it just a bit above idle.

Sounds like air leaking in. Check the gaskets and things. Make sure the carb fits snugly to the head.

It starts up fine, can run for hours. But then it will just die unexpectedly and if we try to start it again, it won't idle then.

Tear down clean it all up check all gaskets do a carb rebuild and you should be good to go.

If it was something gunked up, or dirty, I'm sure the problem would happen all of the time.

The motor can go days without problem, or only minutes. That's why I said it was random.

check and make sure there is no small debris stuck in the carb jet or the emulsion tube.... the smallest piece of crap can get stuck in those little holes and not always block the way, but get stirred up on occasion and keep the fuel from flowing.

also empty your gas tank and add a fuel filter...

I had this same problem not long ago and cleaning the fuel system and adding a filter solved the problem.
