My Cousin dropped by with an engine from a Cub Cadet Original. He's always finding junk since he does clean outs on a regular basis. The engine is complete and looks to have been sitting for some time. I'm not up on the Cub Originals, so I did a little research and realized that this engine is from one. I can't pin down the exact year, but the starter generator date code is August 14th 1962. I could see that both valves were moving, so I removed the head to see what was going on. Right away, I could see that the exhaust valve has a chip out of it and this is the cause of the lack of compression. I removed the valves and the valve seats look good, so I will cut the seats and install new valves. The piston is marked Standard and the bore looks very good. My buddy has NOS rings and valves for this engine, so I'll just pick up a gasket set and do a minor rebuild on it. I might as well rebuild the carb and replace the points, condenser, and spark plug. Luckily the gas tank is clean as a whistle inside and the air cleaner is in nice shape. I don't have a Cub Original yet, but I'll keep my eyes peeled for one with a shot engine or no engine at all.
My Cousin also said that there were a pair of ag tires with rims with the engine, so he brought them by, too. They are old Carlisle Super-lug 6-12 tires on rims with an IH part number. They must have come off of the Cub, I'm guessing. Does anyone know what vintage the tires are from? I don't remember ever seeing Indian heads on Carlisle tires before.

The tires are size 6-12, Pete. They have some nicks in them here and there, and there is a dry rot crack along one of the sidewalls.

I removed the piston assembly to check things out. There is still machine marks on the crankpin and the crank to connecting rod clearance is less than .002. I guess it's hard to find the piston and rings for these small bore k161 engines, so I will take my rigid hone and hone it to accept a standard K181 piston and rings. Luckily my buddy has them, but he has to work overtime today. I'll be picking up the piston, rings, and valves tomorrow and put them with the engine. It will be a good running K161 when it's done.
Just going to edit this post. The bore measures well within standard bore specs, so I did some searching and found an NOS standard piston and rings to install in this engine. I took the old Carter model N apart expecting the worst, but it survived storage well. There is just a slight haze on the brass parts and no varnish plugging things up.I'll replace the needed and seat and the bowl gasket, and give it a good cleaning.
