Dad, a mechanic back in the 40's, always preferred for the valves to just barely be audible under max load. I always backed it off a bit more. It's hard to hear the valves in the coach. I need to get someone to do some real time adjustment while I drive with the hatch off...(or vice versa). No future in doing anything until the new distributor gets here though. I've asked Dick for his timing recommendations with the new dizzy.
