I've never looked at the gauge to be honest, but if a motor can pull 21" at an idle of 500, gotta think it can pull a few inches of advance while cranking at 300rpm (or whatever they crank at).

I don't know if it's a material amount of advance or not, I'm kind of picking at nits here, but figured I'd mention it...
