CR125 Help

[cotttonwoody]

I have a problem with my 92 cr125. It only stays runnin at WOT. Soon as you try driving around at 1/4 to 3/4 throttle, it will almost INSTANLY foul a plug. I am sure it is something to do with the carb. The carb is clean. What jets should i look at, i know the main jet is fine. Or could this be some other problem.

it might be running waaay too rich..

Sounds like it might be the needle jet. Try moving it down a notch or 2 and see if it cleans up. Also, if your running cheap 2 stroke oil, or mixed way to rich, it'll do the same thing. I don't know how long you've had a 125 or anything, but don't forget its a little 2 stroke. They don't like cruisin around.

Well i raised the clip on the needle, this seemed to help. I might try to adjust it a little more. Thanks for the help
