My car stinks!

[rustomatic]

I like the "teary eyed" part of this scenario--it makes people think I have emotions. If the motor gags at .5 turns out, a whole 'nother turn seems like a long way further; half a turn less should be happier (normally)...

Seriously, the double-pumper sounds like too much carb, unless you're perpetually in a drag race. On that note, 64 sounds tiny, unless you have 7:1 compression. With a mild 302 and 10:1 pistons, I've needed at least 68s on the primary side to get rid of pinging. My 570 Street Avenger works great with stock jetting and a 9:1 (supposedly) X302 crate motor (.300/.500 cam and 1.94 intake side + Edelbrock RPM Air Gap). This leads me back to the double-pumping stuff; it sounds like you're just dumping way too much juice down at all times...

It's two cents...
