cast iron Prestolite/Pertronix ignitor conversion

That's pretty cool. The sun machine I can see about half a degree on average. Most of the points distribs are +-2 in the specs. I have to play around with a newer P unit and really see how accurate it is. The cam lobes definitely wear unevenly and they have to be perfectly centered on the dis shaft. I have thrown out quite a few that I would deem unacceptable.
