Coming from an era when a dual point and a 50,000 volt coil was the cats meow I too am getting older. Sometimes I think all this new fangled stuff is a waste of time. Use a drilled cap to set the rotor phasing. Was down playing with it today and looking at the directions for the retard and realized it stayed in the retard mode until 1300 rpm. The starter saver I was using didn't do that. Was adjusting the rotor at idle. Figured it was worth a shot so I moved the dist a few degrees and it started fine. Not 100% sure it will fix the problem but it seems to have at this point. Will be doing some rotor phase testing before the season starts.
