All my 1972 Duster seems to be having electrical issues. I have done the following:
-New battery
-New heavy cables
-New ignition switch
-New starter
-New starter relay
-New ballast resistor
-New coil
-New Distributor cap
-Pertronix electronic ignition conversion
-New plugs and wires
-Additional grounding cable from cylinder head to master cylinder bolt on firewall
I take a spark plug out and hold it the the engine block while bumping the starter relay and I get spark and the engine cranks beautifully. When I put the spark plug back in the cylinder head and try to start it with the key it cranks as it should for 1-2 seconds then it’s almost as if the motor is bound up or like I have a weak battery then goes back to cranking ok for 1-2 seconds then binds up again. The moment I release the key it shoots smoke out of the carb. I then go pull a plug and try to bump again from the relay but now no spark. I’m at a loss, can anyone point me in the right direction?
