(Has this engine ever started properly with the Pertronix?)
Yes, real reliably for the 6 months since I got the Pertronix.

(If you're getting the hot lead for the pertronix from the plus side of the ignition switch (OEM), then you don't have power when the key is turned to the start (not the on) position.)
Not sure about how the hot lead is wired. I know I ran one wire up to a permanently hot spade connector on the fuse box (not fused), maybe that was the hot lead for the Pertronix. But the switch never goes to the start position because I already have a push-button starter switch.

Only problem I have found so far is erratic charging from the alternator, acting like a poor connection on the alternator post. So tomorrow I will clean up all the connections and maybe do some soldering, and see if that goes away. It started right up after 8 hours on a trickle charger...maybe this is about a low battery, or maybe a starter that needs brushes. The investigation continues. I am happy I have another vehicle. Thank you for posting.
