I'm trying to understand how this happened and what the function of this part is. The engine has compression and continued to run after the failure until i turned it off but was way down on power. The damage on the tip of the brass tube is obviously concerning. Im trying to decide if this is a good candidate for JB Weld because I don't understand internally what connects to that could have led to this failure.

Looks like the governor shaft. Keeps engine speed steady. Was this on a mud bog deck removed mower kids toy?

That might be a good JB repair candidate. I would degrease both pieces about three times and scuff with sand paper and a wire brush. Recommend brake cleaner, did I say that. I hate that stuff but it works for repairs like this. Prep it really well like you are doing surgery on it.

ahh this makes sense. it was on an old snapper RER that had a broken throttle and choke linkage so it was zip tied at high throttle.

i see what you mean by the governor shaft in this video of another briggs engine
Do you think i can jb weld this without taking the engine apart?

no

Bert, you should have capitalized that.. NO

NO is correct. Opened the engine and the entire governor assembly was destroyed and that is what pushed the governor shaft out of the engine.

That sluminum boss where the gov shaft exited the block could of been JB'd on. I figured it was some super stock mud bogger kids toy.
