    I'd be pleased to offer instructions and timing values but I need to know what octane gas you use,...

    Thank you,...

    Assuming that you have a timing light and that your point gap is spot on, loosen the distributor hold-down and rev the motor to 6K for a brief moment while turning the distributor to get 30 degrees total timing. The timing marks are on the lower crank pulley, as you know.

    It might take a few tries to hit the 30 degree mark and don't forget to tighten the distributor hold-down after you are done.

    Thats a conservative number for your hot weather.

    Hope this helps,
