Hello, I bought a Mopar distributor from FBO. It was suppose to be setup for my combo. I bought it for a new 470 street combo. When I tried to start the car it had no spark. Threw the old distributor for the original 383 instant fire.
I realized the pickup gap was way off. So I set it and tried it again. It popped right off. But if I gave it any gas at all it loaded up and backfired through the exhaust. What could be causing this? Should I replace the pickup? Good thing I paid extra to have this setup for my combo. Thanks FBO




Could be the pick up or the phasing is out
