Update... Found something strange. It has nothing to do with the installed vs uninstalled distributor. It's the rpms. When the distributor is turning slowly as starting, no fire. When you spin it quickly by hand fires great. We have tried a net Mopar distributor with same results. Air gap is correct
Heavy red to battery. Heavy black ground. Orange to positive coil, black to negative. Red to ignition. 2 wires in plug to magnetic pickup. White not used/taped off
It's just strange that with the distributor out it fires fine. We tried grounding the distributor uninstalled and fired fine. Also fires when distributor is uninstalled and not grounded
Checked that and it's good. What confuses me is that if you turn the distributor without it installed it fores as it should, but when installed no fire
