Here's a deal that I couldn't pass up. It was a craigslist buy from a guy getting rid of this k241 with a cracked piston for $40. It also came with the PTO pulley, ignition coil, two carburetors with air filter housings (one looks like a new aftermarket) and the engine appears to be complete except the muffler. There are small miscellaneous parts missing but it's well worth the price.
He said it needs to be bored but I don't know if he meant cross hatched or bored out. Can anyone tell me how to figure out what it needs other than a piston? I've never rebuilt a Kohler engine before. It will be a while before I actually get to it but any tips or how to get started would be appreciated. He said it turned over but he couldn't figure out why it wouldn't start until he pulled the cylinder head. He replaced the engine and wasn't going to spend time on this one. The bore has light surface rust but no deep scoring. I got the impression that he knew it has value for parts but thinks it is not worth fixing. I'm not at all experienced with these engines but I'm thinking it can be revived and well worth the effort.
