Thank you,
Roscoe Clyde.

Did you happen to replace resisted wire under the hood with resisted wire?
What kind of voltage readings are you getting off the positive side of the coil when the key is on?
resisted or unresisted coil?

Agree to check the vacuum advance diaphragm in the distributor with a vac gun to make sure it not leaking, but it sounds like you may have some trimming up to do on your carb adjustments, or the carb wasn't rebuilt correctly.

I initially changed the wire with resistor wire and then changed it back to the factory wire. Either way I got like 10 v at the + on the coil. It could still be an issue with the distributor or the carb, just seems strange it would be the same issue with two different carbs and distributors. I'll check the diaphragm first. Either way, I'll get it figured out. I probably just put something on wrong.
I do appreciate all of the responses.

Thank you,

Here's my issue. Getting 6 volts at the coil with the switch on, but it jumps to 12 when it's running. Shouldn't she only get to about 10 at most? I have already changed the resistor wire twice, so I don't believe that is the issue.

Any thoughts would be much appreciated.

Please and thank you,
Roscoe Clyde

ignition switch? Check the voltage on both the resistor attached wire and the ignition/solenoid wire right before the ignition switch where they are spliced together in the switch to make sure your getting the same right out of the switch. Maybe the switch is crossing current between the start and run contacts internally.

Not really sure what the issue was, but I got her running pretty good now. Just wanted to say thanks for all of the help.
