Lynn, is there ever a need for the spark advance to go past 30?  This is a graph of a couple of the short runs I was making today.  The advance goes up to 33.2, but it went as high as the mid 40's.  It is so erratic, because it is hitting up against the rev limiter which I had set to 3600RPM. It uses a fuel cut algorithm, which is why it is so choppy.

I need to get it running with less throttle, so I don't have to have it open 35%, then I can get a cleaner graph...but I'm just wondering if I need to beat back that advance first.
