Too much cam?

I'd degree it in to Comp specs and change convertors. Your engine combo is
pretty balanced and nothing there seems too much. Have you messed with the carb much? I'm not familiar with that carb but I would suggest a vacuum secondary carb for a automatic with mild gears and a stock convertor. toolman

The Street Avenger has vacuum secondaries. Messed with the carb many times. I tried power valves 5.5, original 6.5, 8.5 and 9.5. Tried switching the accelerator cam position, changed jets, adjusted the idle screws for maximum vacuum, (15 lbs--rock steady). Now, I don't believe it is card or ignition related.

If the cam was indeed installed 2 degrees retarded, would it cause the hesitation that is overcome by advancing the initial all of the way to 25 degrees? I'll go to Harbor Freight and get a dial indicator and base, try and degree the cam.
