I installed new motor mounts and that made a HUGE difference. They’re the “softer” style from eBay.

It's been a little while but I finally got to work on my K301 from this tractor. The k241 is under powered to run the deck in any kind of thicker grass. This engine did not want to run at all which is why I pulled it, so I started taking it apart to see what was the matter and I found a badly scored piston and a load of carbon in the top end. I also needed a new oil pan because there was only one bolt holding the engine down when I took it out, and the motor mounts chewed up the aluminum. I felt over the bore very carefully and it doesn't seem like there's a any ridging on the top or bottom, so I decided to order a piston (Thanks Lew!) for it and replace that and see what happens. It is a cheap (maybe temporary) fix. It had a standard piston, which measured fine (Except for the top where it was chewed), and measured the bore in several spots. I checked the ring gap in many different places and all measured fine on my non-precision equipment. So I de-glazed the cylinder and installed the new piston. Cleaned the carbon out, and reassembled it with a new head gasket, reinstalled a replacement cast iron oil pan (thanks dvogtvpe) and reinstalled the engine back into the 1250. She fired right up and purred like a kitten after I dialed the carburetor in. No smoke at all, and I didn't see any blow-by coming out the crank vent. I know that's not a "proper" rebuild. I am following the break-in procedure now, and we'll see how long it holds up. This isn't going to be an every day tractor, it's going to pull a cart around and do some plowing, and maybe some mowing.



I am wondering though, where should the governor spring be on this engine? I have it in the third hole from the end of the governor arm and the second hole from the end of the throttle arm. :bigthink:
