OK - the weirdness continues.

I rotated the Pertronix magnetic rotor 1/6th of a turn on the distributor rotor. If it is the problem then the bad cylinder should change. It didn't. So the problem is NOT the Pertronix.

I got an old Beru lead and swapped it onto the plug and the distributor. It also does not pulse properly.

I checked and double checked the distributor cap, which is essentially new. It looks perfect and has zero resistance across it. The segment isn't bent or misplaced.

I don't want to swap out the cap - it'll be a nightmare and I'll end up with broken leads.

Sitting here, I suddenly wonder what the timing gun is telling me? Is it telling me that there is no pulse going to the lead OR is it telling me that there is no pulse going THROUGH the lead to create an inductive response? Maybe I'm at the wrong end. Perhaps the spark cannot jump the plug due to fouling?
