Ok so I have a 31 model a that will run great then out of nowhere run terrible. I’m running a downdraft carb with a 97 on it. Rebuilt distributor with modern points. New wiring. Someone had mentioned that the model a coils need to have a resistor. Is this true? I’m running an old echlin ic55 coil in it right now and no matter what coil I put in it iit still has issues.
