Hi Guys, Looking for some advice, We rebuilt this k241 with a +.010 piston, Its had a rebore to +.010 but they did it off the manual specs and not the piston. Not ideal with an aftermarket piston but I wont get caught on this next time. Its developed this oscillating ting noise, its not the metal cover its there with it on and off, its 100% from the cam side, does it under low load / slow idle, Have setoscoped the motor with a screwdriver to the ear, and I cannot locate it. but its in the top. Have rechecked valvel clearances x2 already , 1st before initial run, and again day after, very minimal adjustment made after 1st run. Ting noise clearly heard in the video , appreciate any advice.

Hello, I have a k241 that I bought a while back and would like to start on it some time this month. It has a cracked piston and the guy I got it off said it needs to be re-bored. By using my dial calipers at the top of the bore it appears to be a standard bore. I downloaded the service manual so I can probably handle taking it apart. Do I just start disassembling it step by step by the book? and what tools will I need for checking specifications that will be sufficient? I have feeler gauges and dial calipers but nothing for inside the bore. It seemed like a good deal for $40. It is nearly complete except the muffler, I also have parts in a box such as shrouds, pulley, cylinder head, coil and a couple carburetors with air filter housings.

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.
