OK, I have a new quick fuel 750 DP mechanical secondaries on 351W. Motor runs fine, idles good, accelerates decent till I hit around 3/4 to full throttle, then it craps out. I have changed squirters to 35 primary and 37 secondary, I have changed secondary accelerator pump to 50, still have problem.
If I stay in accelerator when crapping out it will clean up. No black smoke or anything just craps out, like gas is turned off.
I have good fuel pressure at around 7psi at regulator. New Holley electric pump good to 16psi and new quick fuel regulator...
Getting frustrated, thought I would ask some questions here seeing it is the weekend and quick fuel is closed and it is 75 degrees out in november, would really like to do some driving.....HELP!!
