I have a delema with the new motor. When i am running it it will just shut off when it starts to hit higher revs. I have lots of smoke coming out so i dont think I am too lean, I know I am rich on the bottom as it sputters when first accellerating, But it will make a few good passes then I will give it wot the motor will rev the truck will take off and then as it reaches I wouldnt say max rpms but pretty high rpms it will just shut off instantly. i have tried going richer. If I go way rich to where the motor wont rev high then it doesnt happen so i lean it down 1/16 turn at a time and just about the time I am getting good power and the motor will rev up without sputtering but still producing lots of smoke it will start the killing thing.
any ideas would be appreciated.
I do feel it is broken in now and I have removed the extra shims
