Hello out there, hope you can help me. I have a Briggs 25HP V twin engine in my tractor model 445777. I rebuilt the engine recently due to a catastrophic failure (piston broke) and replaced the governor as part of the work. The engine is running now, but the governor is not regulating it and the engine is racing. From what I can see the governor inside the engine is not pushing on the governor lever so the engine is running full throttle. I've removed the sump cover a couple of times now (and getting tired of it) but I can't see anything wrong with the governor gear. It spins freely and the weight arms do open pushing that little cone out, but it doesn't seem to do that when the engine is running. It installed easily and I have the lever springs installed correctly. Only thing is I bought a used governor not a new one, but the part number was correct.
What am I missing here?
