1950 Plymouth with factory inline 6. No spark after coil. I have tested the coil lead to ground and get a good spark with points open and bridging with a screwdriver. No spark from that point forward to any plugs. I'm going to presume the issue is with the distributor but don't know how to test it. New coil, points condenser, plugs and wires. Points are gapped at .020. No signs of cap cracks. I've had a difficult time finding a mechanic locally who is willing to look at it since it doesn't come with a port for plugging in their diagnostic computer. Any advice on how to proceed with the diagnostics would be much appreciated.
