By the way, as far as I know the distributor is stock Ford. I do believe it has been replaced in the past, but not by me. The guy I bought the 79 parts truck from said it hadn't been run in 6 or 7 years. And I have had it for over a year and a half. But all the wiring is not stock as it is a 55 cab and I put all new gauges and switches in except for the 55 headlight switch and heater switch. The starter and alternator are from the 79 F150. I may have to rebuild the carb to, I don't know, but want to find THIS problem first.
Jim.
