I've got a cub cadet from a box store with a 20 horse Kohler Courage. I know this is a throw away unit but I have really been pleasantly surprised by it. I maintain things well so it should last for another few years. It currently has 211 hours on it and starts well and has good power.
The valve cover was leaking so I pulled it off today and put a little Permatex on it. When it was off I noticed that there is a lot of play in the rocker arms. When the valves are both closed you can wiggle the rockers pretty good. If I remember right something about this is a compression release.
My question is - what about these engines makes them about a 400 hour engine (or so I have heard)? Valves? Seats? Rings? When it is close to shot I will retire it to pulling the sprayer and buy a new rider for the farm. I just kind of want to know if I will suddenly have a window in the block or something.
