Says leaded fuel on the 76 engine---wonder if the seats shouldn't be replaced with harden seats?

Only reason I'm checking is because I get a random back fire through the carb sometimes when under load around 3000- 3500 rpms... I have new plug wires, plugs and new cap and rotor are going on Friday night when I get to the lake house. Sorry for the hijack on the tread JayBrown....

Thanks

Set timing in neutral at idle. This should be approx. 800-850 RPMs.

If you are backfiring through the carb under load, you likely have a problem with your ignition system. Start by checking voltage at the coil + with key on/engine off and while running. Voltage reading should be same as battery voltage, or at least very close. If you are good there, you will find your problem within the ignition secondary components: Distributor (including cap & rotor), plug wires spark plugs. You may have a worn bushing in your distributor.
