I posted on another section a question "what should I gap my plugs to now that I have pertonix ignitor, wires, and coil" but no answer... if anyone replying to this post knows, any help is appreciated. I have a different problem now. I have a new carb from holley that claim to have pre-adjusted needle and seat and "never have to adjust" but I am wondering if there is a problem... my car stalls when I brake harsh (fast) going from whatever speed to 0... and has a little bit of trouble starting up (needs half a pump or a pump at the gas pedal or else it cranks for a while before starting) Could that be the float that DOES need adjustment or maybe... I was adviced that the vaccum advance is the culprit and I need to change it?!?!. The timing seems to be ok... thats the first thing I checked. Help.
