Unidentified metal piece fell out of oils drain

[Cianfich]

While changing the oil on my snowblower (tecumseh HMSK80 engine) a metal piece fell out of the pipe that drains the oil. Photo attached. Any ideas as to what this is? Thanks!

To me it looks like part of the governor yoke, which has been flying around inside the crankcase for awhile. I would test to see if the governor is operating properly.

Thanks! The engine hasn’t been hunting, but it seems to lose some power when it encounters snow. The broken pieces do look a lot like parts of the governor gear (see picture).

It could also be off the camshaft's ACR weights.

The only real way to find what fail is to open up the crankcase.

I loan you my miniaturizer and transporter if you promise to return them before I sent.them...as I will need them yesterday.

Now there is one possible way to inspect the governor and camshaft. You might be able to use an inspection camera but it will be tricky to get it position right.

Works the other way round
Without a functioning governor the engine will race away till it revs past the tensile limit of the connecting rod then it stops forever .
