I am repairing my 5 hp mulcher engine 133432 1041E1 990107YA which had developed some loose parts around the throttle assembly area. It became apparent when the engine would only operate at very high revs, perhaps too high, no matter where the throttle was positioned.
I found that if I manually moved the governor arm to the left then the revs would decrease but the lever does not move that way of its own accord when the throttle is reduced. This model does not have a return spring so what should be making the governor lever move towards the idle setting?
