Briggs governor

I have a Briggs on my Permagreen that was made just for this machine [believe it's 6hp]. Well yesterday the engine went from 3400rpm to a billion rpm [sounded like it anyway] in a split second. I took off everything so I could see the linkage and it is fine all the way back. Can the governor be rebuilt or am I screwed?

Just a SWAG(scientific wild a$$ guess) but two possibilities:

Inspect the carb to make sure the throttle butterfly is operating properly--I've see a couple of cases where the butterfly has come off the throttle shaft.

More often than the throttle butterfly problem above is the disintegration of the interior governor assembly, #46(if I remember correctly) in the parts breakdown.

Since you provided no engine numbers, I'm just guessing it's a typical Quantum engine.

Unfortunately the butterfly was good, one of the first things I checked. I could not find any numbers other than the Permagreen part number. It is the basic mpwer type engine other than it has a extra 3/8 (i beleive the size) PTO shaft out of the side to run the spinner pn the fert hopper. I was just wondering if the governor could be rebuilt.

Depending on the age of the engine, you will likely find the engine numbers stamped on the blower housing above the plug. On later engines you may find the numbers stamped on the shield above the muffler.

If the governor is shot, it is not rebuildable--replace the assembly.
