Thanks a lot, I will check all those items. The backfiring did blow a hole in the muffler, so it’s a bit noisy. It’s 30 odd years old so I can’t complain about that. The distributor cap sounds quite possible. It’s not old but it is Chinese made and cheap looking. It all started all of a sudden after making a long drive on that weekend and then the trouble started when I was about 100 miles from home.
