I disable them all, they just seem to work better without it. I've had no problems yet. As far as adjustment, I always have the carb apart anyway so I just adjust it to whatever it needs when I'm done.
If it's a 420 it probably has a tilly HS, so yes it will have a govener.
Well I just put a kit in the carb and there is no govenor on this tillotson.I think my other old partners may have walbro's maybe ?
