No offence taken, if I did not want sugestions I would not ask.
I had allready decided that I had only the magneto coil, ignition coil, condensor and wiring left to look at. What I was hoping was that someone had seen these same symptoms.
What really bothered me was the cycle time of the problem, 15 mins on, 15 mins off. I would have though that once I got something hot enough to fail, it would fail again quickly the second time.
Anyway, read my other post for an update.
