About the points eliminator set screw. after the autocross at Carlisle this spring, my car was acting poorly, missing at high speed. Ran and could be driven, but was poor. I dis a few things on the engine, not the least was to buy a new coil and Pertronix unit. Old device was (as listed here) Compufire. When I went to replace the old Compufire module with the new Pertronix (all made by the same compant, as far as I can tell) I found the set screw loose. Hmmmm . . . ANyway, the new coils was installed and the new Pertronix, with a very tight set screw, AND some blue Loktite. I can report that the engine started almost before I touched the key, I mean instantly, after sitting for a few months. Not sure what was exactly wrong before, but all is jake now. Runs good, ,strong, smooth, and winds up tight, like it should. I do not know what Carlos is dealing with here, but it very well could be ignition. BTW, this "total rebuild" of my ignition cost less than $100 - a new blue coil and the Pertronix. Simple.
