SOLVED!....sort of. Where's there's spark.. there's no fire!

Yes, there is tracking, but I didn't think it was bad enough. Perhaps I was mistaken. Thought I might chisel it in the morning.

Pretty sure the coil is atop the cap. Distributor is this one.

Getting to town is a little tricky. Hoped to diagnose as much as possible beforehand. Seems to be pretty good consensus here. I'll try the chiseling and coil connection first. If no joy, then try and find a new cap and rotor.

Thanks!
