    Gary, I've cleaned every ignition connection as well as tested the coil and magnetic pickup, but nothing found so far. Also, I tested plug wires. I'll be swapping out coil & pickup over the weekend. I'll let you know how I make out. Fred

    Fred, you may need to rig up some LEDs as visible test leads to show if a 12V supply goes missing momentarily. Also check all your grounds are clean & tight. Gary

    Gary, problem solved. Bad coil. As soon as I swapped out the coil, ran like a champ. No more miss. No bogging. No stalling. Coil tested a little low on the ohm test but nothing else showed. Pickup tested fine also. Thanks for the help. I enjoyed every minute of the trouble shooting. I teach High School electrical engineering so that helped with all the multimeter reading. I never put in the new magnetic pickup because I couldn't figure out how to do it. I thought it would just be a simple remove the 2 nuts and take it out. Apparently not. I couldn't find a good video on it. If you have any specific info on how to do it, please send it to me. thanks again. Fred
