Car bucks/bogs when decelerating, Holley 4160.

I have been fine tuning my holley and after ''properly'' adjusting my floats the car has developed bucking when decelerating. Only similar thing is like its running out of gas.

This problem was not present when the floats were not adjusted right and removing the sight plug would have fuel pour out everywhere. I adjusted the front to where it bearly dribbles out the sight hole and rear to where you have to rock the car back and forth to get it to drible out.

During a test drive tonight, I noticed the car shaking and doing it very severly. I pulled over and turned in the idle adjustment screw all the way in and the problem was reduced. It still did it very faintly.

Any ideas? Acceleration and wot seem to be pulling way better than before though. Only this problem is present.
