Sorry this is a long one. 52 8n side mount distributor. Has been running rough lately. It runs fine after a few minutes would act like it is choking up and stalls. Will start after a little while and seems to run ok. Kept getting worse. I did find a blown head gasket. Pulled head had it surfaced and reassembled. It ran much better but was still having the symptoms mentioned above. I had a 12 volt conversion kit for years so put it on thinking it might help having all new harness. It seems to be worse now. I put new points condensor distributor cap and rotor copper core wires and plugs. I seem to get good spark at points but weak at the plugs. I even tried other coils I had around. Good fuel flow. I even put another carb I had still acts the same. I need help desperatly. Any suggestions.
