Ignition Help

This suggests you're getting spark jumping from the carbon centre button to the rotor spring. Use a BlueStreak cap (CH-409X) and an Echlin long-tip rotor (MO-3000; make sure the one you get is tan and not white). Before you install the rotor, bend the stainless spring firmly upward (by hand) so it'll make firm contact with the cap's centre button. Then carefully but firmly squeeze its rivet with a bench vise or ChanelLock pliers to make sure it's firmly set. That should solve your cap burn-up problem.
