Need help tuning carb!!

I have throughly cleaned my carb and now i cant seem to get the air/fuel mixture screw set back where i had it.

I dont have the stock air filter and i have drilled out my main jet so screwing it 1 1/2 turns dosent help me much.

I think it is running rich right now. It will accelerate well till high rpms then sputter and die. If I run it on the kickstand, it will blow white smoke and act like it is governed.

Thanks in advance.

That screw just sets your idle jet, so it should be set to 1.5 turns anyway. Your main jet isn't really affected by it. Main jet is for wide open throttle.

Sounds to me like you're running lean if it's bogging out. Need a larger jet, IMHO.
