Well, I've cleaned the grounds 2x, last time, I took the 3-pole copper tab off the bolt off the top of the engine, hit both with a wire-wheel (dremel), & cleaned the tabs with a wire brush, brake-cleaner, & pinched them down for a better ground, cleaned all the other grounds, all relay contacts (just in case), still only 1/2 fire.

I also pulled the disty, then the trigger points: visually look fine, washed them hard with brake cleaner, & re-installed. I have both a used computer & wiring harness on the way: I'm hoping it's one of those.

Now, the trigger points are installed at the base of the distributor: mine were clean as they came with a rebuilt disty I had recently purchased. I could always swap in my old trigger points, but it appears there's not much to fail except when excessive grease/oil is introduced. Correct?
