Distributor/Electrical Issue

[6lucky13]

Recently my car (Avatar…1936 with ’37 engine) started to miss under load…first and second gears. I planned to change the condenser (FA49) but drove the car in a local 4th of July parade. There were no issues at the slow parade speed and car did not overheat...max temp about 200F. After cooling down for about 2 hours, went on the trip home and, after about 2 miles, the car stumbled badly and had no power. Towed home.
The terminal caps showed damage at 2, 4, 7, and 8 electrodes (see photos). Based on the firing order, I suspect a problem with one set of points (?). Distributor looks fine to me but I don’t know what I should be looking for! The rebuilt distributor had about 2250 miles on it as did the Skip’s rebuilt coil and FA 49 condenser.
The only changes I made to the car previously were to replace a failed cutout with a Fun Project cutout (about 400 miles ago) and replace a failed Optima battery with a lead acid one (about 150 miles ago).
Any ideas about what’s going on here?
Thanks…Kerry
