rcign:

I took the carb completely apart and blew out all passages. I adjusted the arm you told me too also.

So far I've got the engine to idle pretty decently. I can go as low as 1500 rpm. But a better idle is at 2000-2200 rpm.

Transission is very smooth and I can only get it to peak at around 6600 RPM.

I can't believe how much a 1/8 turn difference can make.

My only problem now is even at 1500 rpm I can't keep the Giant Stinger from moving. It just wants to keep rolling. Has anyone else had this kind of problem. And this is on rough grass. He he. Maybe I'll put a 22 x 10 prop on and see if that helps prevent the roll out....

Thanks for your help RCIGN.

and thanks for all the other suggestions. I might experiment and drill out the fuel tank clunk in another tank.
