The instructions with Ignitor II says it can change timing by as much as 10 degrees. I have never loosened clamp or moved distributor. Screws on Pertronix were tight, I can recheck. I will put charger on tonight.
It was running fine, from my folks to my house and around the neighborhood for a couple weeks. It stalled out, and was hard to get going again, it would hardly accelerate, got it into driveway, and it did not start again. new fuel tank, fuel pump (which is new too) was taken out and cleaned, all new rubber, steel lines blown out. Carb cleaned again, (rebuilt before it initially ran), inline filter, so I can see gas is getting to carb, carb does jet gas, pulled a plug today after trying to start and it was wet and smelled of gas. I am less inclined to think fuel, but I very much could be wrong. I assume what put it down could have been debris from tank, which seems to have been handled, and since then another problem, seemingly electrical, has occurred. to try and solve this, I have done new points, rotor, plugs, condenser, coil, cap and wires, no change. THEN I did the Pertronix and new coil. No change. the battery is 750 cold cranking amps, and is only a few months old, I will top it off with charge. Thats the whole story as best I can remember.
