Krice58 90 #1 Posted August 23 Working on the 75 C160 with the K341 and I was having a lean condition causing some popping from the carb after heating up. Removed the cylinder head and confirmed a lean condition as the exhaust valve was completely white. I check the valve clearances and the exhaust valve was tight so I adjusted it to 0.019 as per spec and the intake valve was close but I did adjust it to .009 to be sure. Hoping that this solves my problem, but just thinking ahead if necessary. How feasible it to rebuild this engine for your average hobbyist? I’ve done a lot of basic repairs on vehicles (brake jobs, suspension components, engine sensors, exhaust work) and lawn equipment (basic wiring, gaskets and seals, carburetor and ignition work) but I’ve never actually torn a motor completely down and rebuilt it. Is this something that a person can do as their first rebuild? Everything I read says to rebuild the K series instead of retrofitting something else, I really can’t afford to spend several hundred on specialty tools on top of the cost of the rebuild components and potential machine shop work. Again, hoping I don’t need to do a full rebuild, but I’m willing to try if it is feasible for an engine novice. Share this post Link to post Share on other sites
squonk 44,605 #2 Posted August 23 The biggest thing now is finding quality engine parts. I just did 3 k181's and got everything from I Save Tractors but he's no longer in business. Pay close attention to the top of the piston closest to the exhaust valve for erosion. Read these threads! 2 Share this post Link to post Share on other sites

If you have access to a torque wrench and a piston ring compressor you can do the rest with common shop tools. You will need to enlist the aid of a machine shop anyway so let them do the measuring, valve seat cutting and valve installation for you. The grenade gears have gotta' go! This thread will give you some valuable information about the process. 2 Share this post Link to post Share on other sites
JimSraj 549 #4 Posted August 24 (edited) Three years ago I decided to rebuild a K301, that came with a broken rod, that I got when buying a deck for parts. The guy said you have to take the tractor (1267) too. I had never opened up a small engine before and it sounds like you have a lot more mechanical experience than I. Point is ‘you can do it’! Follow the Kohler manual and check all the helpful videos here. Be meticulous, call Kohler if you feel unsure about anything. Their support staff was fantastic and very patient. Ask the guys here, there is a wealth of knowledge and experience members share for the asking. My rebuild turned out great , fired right up and has been a beast of a worker with few issues ever since. Edited August 24 by JimSraj 3 Share this post Link to post Share on other sites
Krice58 90 #5 Posted August 24 After adjusting the valves and tweaking the carb, it seems to be running okay 🤞. No more popping at the moment. A7AACEC4-2A15-4EF6-82B8-264CC5A0D668.mov 3 Share this post Link to post Share on other sites
