Re: High compression head and timing?
I let the engine tell me where it wants its timing lever to be on my high compression head. While driving at fifty or fifty-five I minutely adjust the spark lever to see if my speed goes up or down to fine tune it. Nine 0'clock is where it likes to be at highway speed. It resists at 9:30 and 8:30 0'clock settings of the spark lever.
