If you don't mind I'm going to jump in here with a question. I'm having electrical problems of the same kind. I have a 12 v system. I have a new resistor in the line that goes from the ingition switch to the coil and another line going from the minus side of the coil to the distributor. My foot starter switch has only one post on it, with no provisions for a wire going back to the coil. I am having problems getting the timing right. But think I will eventually get that worked out by trial and error if no other way. The truck is now backfiring through the carberator, which makes me think it is firing too soon. Do you agree with that. BUT, my resistor is getting hot, as are the wires going to and from it. Also the coil while not as hot is getting very warm. This doesn't seem normal to me. What have I done wrong? Am I using the wrong resistor? If so what should I ask for at the parts store? If I bought a new coil with internal resistance, could I then just hook the wire from the Ignition switch directly to the coil, and just forget about the resistor, etc. Thanks for your help. Allen
