OK, but I like to bring the RPM up to mid-90's and check the horn before engaging the governor. Plus, as has been mentioned, having it kick in from 80% could swing you round on a slippery surface.
I'm not convinced that the governor is the best way prevent an overspeed if starting with the throttle open - anyway, if that's the intention, wouldn't it be more to the point to ensure that the throttle is closed rather than putting the governor on ? If you do "Throttle - closed" after "Twists for priming" then you won't get an overspeed.
Thanks for posting the new list csc - haven't we got "Governor on" twice now ?
