Harmut, Thanks for the suggestions. I wondered if a new harness would help. The plugs were just replaced 15 or 20 hours ago. My alternator/magneto guy said that he checked the filters on the mags and said they were within normal tolerance. You have given me some ideas of how to diagnose the problem and how to "brute force" a solution.
Thanks.
