I have a 66 Oliver I'm restoring. I had it running fine. Drove it around the yard for a while and suddenly it began missing and backfiring. Black smoke would roll from the exhaust pipe and it would barely run. It back fired so hard it blew the rain cap off. Twice.
After putting a kit in the carb it was no better. Replaced points, plugs and condenser. No better.
I discovered if I tapped on the distributor with a wrench the engine would run smoothly bit as soon as I stopped tapping the engine would again barely run and eventually die.
I took the breaker plate out and sanded and wite brushed everything until it was shiny clean. Sanded the inside if the housing so the breaker plate would have good electrical contact with the housing. Removed the through stud and brushed and sanded everything for good contact. After reassembly the engine ran fine...for a few minutes. Now doing the same thing.
The bushings seem to be good as there is no side play in the shaft nor any vertical play.
I'm at my wits end. Rather than tap briskly with a 9 pound hammer does anyone have other suggestions to try?
