I have a 1973 Charger SE project that originally had a 440 but at some point had a 1969 440 swapped in. When I got it it had sat for several years. We got it running but bad fuel had the carb all gummed up. I pulled the carb, had it rebuilt and just put it back on with new spark plugs, ballast resistor and high torque starter. Car has an Accelerated super coil and wires, electric water pump and fans. I filled the float bowls through the vent tubes and tried to start it. The car will start to crank but then backfires a fireball through the carb and leaves a small fire burning in the carb. This is outside of my experience level so any help or advice on how to move forward and get the car running would be appreciated. I have read forums saying to check vacuum advance or the colts at the ECU, which I would do just not sure how to do it.
