Hi guys.
Ok, question.
I had a new Dizzy installed and now the car, though runs decent, begins to show the following symptoms.

1. at any constant speed, say 2500 rpms....it sort of lightly bucks. Just not
smooth as before.
2. at temp.....when I hit the pedal quickly, it pauses briefly and sometimes pops!

We adjusted the advance/retard position
we also adjusted the fuel pressure.

Does anyone have another idea? I have Mass Flo and it has been superb
for the last 4.5 years!!!!

thank you for any help
