MSD

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.
I'm not the guy to ask. I don't know much about MSD other than all I hear about MSD is a announcement over the loud speaker at the drag strip that someone needs a 6al box! LOL
