Bad governor
Look on YouTube for video's on how to replace a Briggs governor. There are several there. My favorite, with best explanation, is, "Easily Replace Briggs Governor Gear (V-Twin Intek Engine) with Taryl". https://www.youtube.com/watch?v=wn3eanGxSEA&t=152s.
Taryl (probably not his real name) does a very good job of showing step-by-step the whole procedure, along with some additional hints/tricks/techniques of value.
Not including oil and filter, I spent less than $50 for a new governor, gasket, and drive shaft seal. That's all that is really necessary to replace is those three parts. That is, unless pieces of the old governor tore up a gear, valve, or something else. Inspect everything! {I was lucky and only the governor was destroyed}
One word of note. Be sure to clean out all of the debris from the blown governor. Be sure to remove the spark plugs and carefully rotate the drive shaft while looking for nooks-and-crannies where debris can hide. I tried to use a magnet to help, but it didn't help much, even though the block is aluminum.
Good luck.
