    How to fix a Kohler CH11-16 Engine that cranks but won't start?
    • W
      William SloanAug 12, 2025
      If your Kohler Engine cranks but refuses to start, begin by checking if the fuel tank is empty and fill it if needed. Then, ensure the fuel shut-off valve is open. Inspect the fuel system for any dirt or water and clean it. Also, check for a clogged fuel line and clear it. Verify that the spark plug lead is connected and the key or kill switch is in the 'on' position. If these steps don't work, the spark plug, ignition module, or oil sending unit may be faulty and require replacement. Lastly, ensure the choke is closing properly.

      Joshua GrayAug 27, 2025
      If your Kohler Engine uses an excessive amount of oil, ensure you are using the correct oil viscosity/type. Drain excess oil if the crankcase is overfilled. Check and clean the breather if it's clogged or improperly assembled. If the problem persists, you may need to replace worn or broken piston rings, repair or replace the cylinder bore, or replace worn valve stems or valve guides.
