Overheating on run stand

Thanks Rob, the timing #'s are a ballpark. Watching everything else, I didnt the right timing down. 45 seems like a lot with va unhooked?
I knew temps increased but couldn't remember if it was from advanced or retarded.
It is a lot. It's not under load! You need a lot so it won't run hot. I'd pull in anywhere from 36-45 at about 3000 RPM.
