How to fix a Kohler Command CH13 that cranks but won't start?
- J
  Jorge LoweryAug 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.

Why does my Kohler Command CH13 Engine start but not stay running?

  If your Kohler Engine starts but doesn't keep running, first clear any restrictions from the fuel tank vent. Inspect the fuel system for dirt or water and clean it if necessary. Repair or replace any faulty choke or throttle controls/cables. Check and secure any loose wires or connections. If these steps don't resolve the issue, you may need to replace the cylinder head gasket, fuel pump, or carburetor.
