Wheel Horse C-81 has a Kohler K181S that over revs. I have set the governor shaft as recommended by loosening and pulling governor arm away from carburetor and blocking it while rotating the governor shaft counterclockwise, then re-tightening the clamp holding the govern arm to the governor shaft. The engine still over revs wildly after this has been done. I next loosen the brass nut and rotate the ring clockwise that is attached to the throttle cable in an attempt to contain the over revving. Still no apparent improvement. The governor shaft rotates within prescribed limits, which tells me the tab is present and doing what it should, but does this all mean nothing if there is an issue with a broken or perhaps missing governor gear? The previous owner stated that he had “disconnected” someting from the governor, but didn’t say whether it was internal or external. Is there a way to tell whether nor not something is amiss internally without doing a complete teardown of the engine? I presume the engine will run without a functional governor gear, or is that presumption incorrect? Or, am I missing the problem altogether, and there is something else that could be causing this over-revving problem?
