Don,

Great advice, thank you. That is especially a good thing to know about solid core wires (that generate a lot of EMR) interfering with the Pertronix, but it makes sense now that you have mentioned it.

I did a compression test on the motor around 8,000 miles ago which was fine. While I wouldn't expect that to be different, I agree that you make a good point in case the timing chain has jumped. Those old motors use a double timing chain, but you never know, it wouldn't hurt to do again.

Fuel pump pressure at idle was 5.5 psi, did not drive it around with the fuel pressure gauge hooked up.

Thanks again for the help.
