RAndy:
You should run the cyl head temp at least 180 degrees for optimum
performance. The timing should be set at approx 35 degrees , at full
advance. Depending on the distributor that you are running, this should be
at approx 3000/3500 RPM. You will then have to run premium fuel, but should
show a decisive increase in power.
