I would get a cheap point dist and install a new set of points and see what happens. Electron ignition is great when it works but can cause many headaches.
you be surprise how well a point dist can work and its so simple, cheap and easy to wire up
but alot more maintnace is required, such as cleaning and gapping points every tune up, as well as having proper dwell. electronic ignition is the cats a$$ and is also easy to figure out
