Had a great time Saturday swimming in Winnipesaukee. Got out and stopped at scenic overlook of lake for some pictures. Amphi never ran again, took it home on trailer! I have a complete replacement distributor with pertronix ignitor and a pertronix coil that is about 15 months old. Long story short....Problem ended up being a bad coil! Put in my 50 year old original coil and started right up and spent sunday back in the water! After googling "pertronix coils prematurely dying" it seems like this is normal for these coils. Bottom line is, carry a spare coil!
