NitroFreakManHo-

Clutch and bearings are all new, it does make a blubbering sound when I hit the throttle and then dies. It does not idle down very fast after WOT either!



Maximo-
Engine is stock

Tons of Pinch

Byrons 20%

The first 8 tanks I did small circles at half throttle, then started leaning it out.
I have a 1/4 acre area near my house the I run the car on, a few sharp turns and a few bumps here and there, to similate some what of a track environment.

I was wondering the same thing you mentioned about pulling one shim to see if it helps out any.
