I was given a Yardman 42" mower with a Kohler CV16S, the guy told me he replaced the o-ring on the governor shaft and now it revs wide open if I put it in full throttle. Like wide open it will blow up, when I return the throttle to idle it idle's no problem. When I start the deck the rpms drop and when I disengage it it returns to screaming again like the governor isn't doing anything. Any ideas? Thanks
