I was looking around at some of my treasures and found this Kohler K-121. I didn't know that Kohler made a K-121. I don't know where I got it and I don't have any idea what it was originally on. I thought it was neat that is has 2 exhaust ports to get you the option of how to direct the exhaust away.
That is cool Brian! After seeing the PDF from Bob, Then looking at your engine again I noticed it is the same color as a small Tennant floor sweeper we used to have at work. Nice find! I bet there are not to many of them around anymore :thumbs:
I have found out thru another member that these engines were manufactured for the G. H. Tennant Company.
Web search came up with this,
Founded in 1870 by George H. Tennant, Tennant Company began as a one-man woodworking business, evolved into a successful wood flooring and wood products company, and eventually into a manufacturer of floor cleaning equipment. Throughout its history, Tennant has remained focused on advancing its industry by aggressively pursuing new technologies and creating a culture that celebrates innovation. Today, Tennant is a global leader in designing, manufacturing and marketing solutions that help create a cleaner, safer, healthier world.
It's stuck, so Monday I will pull the spark plug get some penetrating oil down in it. I picked it up in a pile of stuff up in Dallas when I got the M/W Bolens and the Bantam Standard.
I got her apart and it's in rough shape, but maybe I can save it. I will post some pictures later. The crankcase had water in it and the bore is pretty rough.

The problem is so far I haven't found any cross over to any other K-series engines. I was hoping that this used parts from a couple other engine to build this special order engine.
Well, I've broke 2 out of 3 rings trying to free them up on the piston. Now to find any brand engine that has a 2.625" Bore and uses .0935" rings. :wallbanging:
Brian, I do believe the Tecumseh HH60 has a 2 5/8" bore. I can check my spare block tomorrow. Measure your wrist pin, and it's location from top of piston.
Daniel, The wrist pin is .625" (5/8") DIA., and center of pin is 1.3125" (1 5/16"). 1st and 2nd rings measure .0935" and the Oil ring is .187" and is a one piece ring.

Bore is exactly the same at 2 5/8". Wrist pin identical at .625. Problem is, the TEC wrist pin is centered only approximately 1.150" from the top of the piston, so the piston would like about .1625" from reaching the top of the cylinder. You possibly could overcome much or all of that by shaving the head and milling pockets deeper for the valves. Rings don't matter, as you'd simply use the correct rings for the HH60 piston.
