I am not sure how, I am no electrical engineer but I had a shop instructor(also ex-motor pool) tell me that "back in the day"(points & 6 volt systems) that it was often done on cold mornings to help cars start. I have done it many times & it does work. Brian
this is how resistor wires help hotter spark. the coil out put has to buld higher before the spark jumps to ground. i suspect some problem with the distributor and dwell. worn or loose parts. what color is the left fender?
