[Oldtom]

I once had a similar problem with my '28 Sedan after replacing a condenser on the road. Eventually discovered that the fibre washer was missing from the contact end of the condenser and also that the new condenser was a quarter inch longer than the old one. The car would sometimes start and run well all day, or run good for a time, or start and run badly, this all due to the condenser being too close to the distributor housing. I insulated the end of the screw from the dizzy and all was fixed.
