Not sure about the oil only rode it a few times

not enuff air fouling out plug.
it doesnt want to stay runing when it is cold and will not hold an idle

I talked to a local small engine guru and he said to Start at 1 1/2 turns out then go in till the idle is as high as possible then bak it out an 1/8 hope this helps.
That is exactly right!!!:thumbsup:

It might be the carb. jetting. I know that you have to re-do jetting if you add any power adders. Bigger pipe=Bigger jets=bigger air filter.

Imo...Your main needle jet in your carb. is too small(diam.) or up to high. I'm not sure if 4-stokers have a c-ring clip on the main Needle jet but, if it does you have the c-clip to Low on the Needle jet(Rich). The further up you go the Leaner it runs.

*There's a pin in the cam that locks the spark advancer in place if that's not there the spark advancer wont spin and you'll have no spark take the cdi cover off and see if its spinning...just a thought...
