Eager 1 Craftsman 6.25 hp - Governor linkage inside bottom of tecumseh 143.026202 unknown.

[MorrisWills]

Dropped its oil after every session after parked for ten minutes. No leak atop it.

Flipped it and I took it apart from the bottom, observing that the oil seal looked good from that view. When I gently pulled the bottom section from the top, I felt a bit of resistance, which surprised me, and had thought mebbe there was a spring I didn't know about. The old gasket was indeed broken with a crack across the edge. It was thin black rubber, 1/64" thick. I had a sheet of 1/32" McCord gasket, so traced out a gasket and cleaned edges and all that and put it back together, but... there wasn't a gear connection for the governor to be in play. The oil pump was a sleeve that shot out from when the piston rotates, so I understand that and realize thet that shall keep the oil pumping around. I think mebbe had I removed the flywheel, I would have access to look inside the engine and mebbe see how a linkage wire is supposed to hook onto the governor, but mebbe that happened naturally when the two halves came together, 'cause I examined the thing and couldn't discern how that fit. Darned if I can get a good view of it with a parts' diagram, nor online websites. The rotary lawn mower 21" multi-cut model # is 944.362640 but the tecumseh engine model # is 143.026202.
Any advice much appreciated. Great website here. Thanks. M 14/06/25

Thanks for the PartsTree link. I think I'll go into it from the top and try again. My browser kept stalling today, but it'd be a good idea to order the gasket pkg that's available. My mower is ancient.

Parts tree is a pretty good source, but make sure you have the correct model or spec number.
I will say at least many of the old ones still have parts available. Good luck with your project.

Thank you Rivets. Yes I see image 57 shows what ours looks like, and this file also shows a spring which I think might be my target. I shall get back to the forum with progress. Best regards

What is the actual page number are you referring to? The image numbers are all different per chapter.

To AutoDocs: The diagram #57 on page 77 is within chapter 9 "Internal Engine And
Cylinder" , the last topic there discussed "Engine Assembly". Our mower was bought at Sears. Diagram #55 shows a spring, though no such one was evident. The Cross reference chapter 10 does not list our engine, so for now, no help to find a muffler either.
