That's correct Andy, 600 rpm is what's called for and the car tach most
likely is not accurate down that low. Use a digital tach like what is on an
advance strobe. The light across the points when static timing is great but
it doesn't work that way with a electronic igniton. Unless there is another
way, I don't know...Neil
