Allright, after a month of slowly rebuilding the motor on my 76 40, I got it all back together, and am having some running issues. I am running a new weber 38/38 (w/ a pressure reg) with a new non-usa dist w/ a petronix igniter replacing the points and a high output coil.. internally everything was remachined, new timing gears, rv grind cam, and a rebuilt head.. basically everything is new or refurbrished. The car starts and runs at idle, but it is rough. If left to sit idling the engine will run fine for a while, then sputter and pop, then come back up to normal idle, then slowly die.. Increasing the idle speed smooths out the motor.. I get good advance and smooth running if I slowly bring the engine up to speed, but hard depression of the gas causes it to miss then backfire out the carb. Ive dialed in the timing the best I can by ear (anyone know the specs for the non-usa dist?) Could this be a vacuum leak? I was thinking maybe I am getting a leak where I had to pull the factory studs to mount the carb adapter plate? It is driving me nuts!
