I have a new carb (34 PICT) with a new dualport running an old dual vac dizzy with a Compufire ignition. The car seems to hesitate under acceleration especially in 1st and 2nd gears. The hesitation is especially noticable when the car is cold. I adjusted the timing at idle with a timing light. I also adjusted the carb but I still have the hesitation problem. My question is what could cause it? One thing I wonder is if I adjust the advance the RPMs increase. If I then adjust the carb to lower the idle it throws the timing off and I must advance the diz again. At what point am I really at correct advance??
