I will rebuild your k161, K181, K241, K301, K321 and K341 cast iron kohler engine for 275.00 plus parts and machine work if required. In most cases cylinder will be bored, crank will be ground, valve seats ground or reconditioned. New piston, new rings, new rod, valves new or reconditioned, all new seals and gaskets. Entire engine brought back to factory spec. I no longer do performance/pulling engines or twins.
If your old Kohler is knocking or smoking it's most likely time for a rebuild before it locks up on you. Once rebuilt, and properly maintained, it will give you another 30-40 years of service.
I don't cut corners, I take my time and get it right. 40 plus years of working on and rebuilding k series engines. You won't be disappointed.
I also have several completed engines for sale both dressed out engines and long blocks.
