I was pulling my hair out (ok, not really. I shave my head.) when I couldn't get my car started. Thinking it was the fuel pump, I swapped it out for a new one. Still didn't start (now I have a spare!). Checked the spark, and no fire! Brand-new, rebuilt dizzy from Advanced. Traced my juice all the way to the points and no spark. Started swapping out parts....condensor, coil, rotor...Nothing. So, I slipped my Pertronix in and KABOOM, it started with a vengeance. Runs like a bat out of Hades. Go figure. Now, these were all Jeff Schlemmer's components. His cap, his rotor, his...points...it was the whole points assembly that was bad. I reused my old Sport coil, and his new cap and his new rotor. It was the points. For the life of me, I cannot bench test this points set with a juice machine and get it to fail. A real enigma. Just be satisfied with the Pertronix, prolly get a spare to carry for the road. Might go back later and reinstall points using one of my many new sets from TRF, standard Lucas.
