Outdoor Power Equipment and Small Engines - Wizard rotor tiller

I've got a rotor tiller with a horizontal shaft Briggs and Stratton engine. I've done some work on it and it starts and runs fine. However the governor seems to be not working right. When I start it the engine tries to run faster than wot. It does this wherever I set the throttle. I can take the throttle valve on the carburator and operate it between idle and wot. When I do this, I can watch the governor and it doesn't move. Should I pull the engine apart and look at the governor and see whats wrong? The numbers on the engine are: M - 130202, T - 0135-10, C - 73091407. Any ideas would be much appreciated.

It wouldn't be a bad idea to check inside, easy to do on a horizontal as well, just make sure to have a new gasket handy.

I agree, the governors on those engines have problems sometimes. Sometimes they don't hold onto the stud that they ride on, and come apart.

Thanks for the advice V8driver and cheese. Think I'll go into it and see whats wrong.

I'm afraid this one's junk. When I got it apart there was a long gouge (from top to bottom of the piston travel) of its cylinder.
