Thanks for your thoughts, Otto.
Yes, I plan to look into the ignition ...again.
I also have a store of NOS distributor parts (points, rotors, caps, condensers) from eons ago.
Unfortunately, Jon's condenser/cap will be too darn pricey by the time it lands in Canada here.
I'm also toying with the idea of solid state retrofit (ie, Petronix) for the distributor.
That theme was popular even back in the 60s'!
But first, I wanna exclude the usual suspects.
