I'd put a vacuum gage on the intake manifold and adjust the carb to get the highest vacuum (15-20).
How do I adjust the carb to change the vacuum pressure? I have a 2 barrel carb..

It will also tell you if the ignition timing is off. Set your timing at 12 deg., dwell at 30.
12 degrees before 0(TDC) or after? Also I am new to these points distributors, how do I know set the dwell, I know its an Allen key screw inside behind the dwell cover but how do I know when its at 30

make sure your plugs, wires, ignition cab and rotor is good.
They are all brand new
