Hi, I have a 51' Super A that is dieseling when hot.
The engine as been rebuilt with 3 1/8" stepped piston in the 80's. The compression is still good and quite equal around 130 psi. It's easy to start and runs perfectly.
I tried running it with supreme gasoline 92 octane, it helps but still dieseling.
Is there something to do or check to cure my "little boy"?
