Lawnmower has gone crazy

I have a 18 HP Kohler engine in a 42 inch craftsman mower. I was mowing the other day when the engine started to really go fast. It made the mower go really fast also. I checked the belts and seemed ok. I turned it off and still accellerates very very fast. I kinda think it is the Govenor by looking at my owners manual, but really not sure. Does anyone have a suggestion? If it is the govenor, does anyone know where it is on this particular engine?

Also I did look at the cable that goes to the throttle and seems to be entact

I'll bet the throttle shaft has worn in two, or the throttle place came out of the carburetor. Give it a look. If so, you may have those parts imbedded in the top of the piston. Hopefully all parts are still in the carb or intake.
