Re: V6 305 distributor issues
If the backfire problem started only after distributor replacement, chances are that the initial ignition timing is too low. 1963 was the first year for the 305E, and the initial timing for the engine was 7 1/2 degrees BTC with the vacuum line removed and plugged. IMHE, backfire problems usually are caused by low(slow) initial timing settings after distributor replacement. If the engine was backfiring before distributor replacement, chances are that the accelerator pump circuit in the carb. has failed, requiring a rebuild of the carb. I hope this information has been helpful.
