quadrajet question

[holtjohn]

I just put a motor in my car that has a quadrajet on it, that seams to work great except under one condition, very light part throttle. The car bucks and pops at part throttle give it a little more or less throttle and it runs great. What could be causeing this issue?

neverminds guys I figured it out. DOH #-o #-o #-o I stabed in my race MSD pro dizzy set up for my race motor, with the vac advance hooked up it was pulling to much timing with the light springs.
