That is what I think as well. But does not the MSD Dist. have another way to limit when centrifugal advance comes in? I am right near perfect on the tune, idle speed seems to be perfect, other then it increases like I posted. Cold idle is 1000, no choke. as it warms up, 1200. Gets hot,180 degree, goes up to 1800. Still runs great no matter the temp.
