Why won't my Kohler Command PRO ECH650 engine crank?

Mark LawrenceAug 22, 2025
If your Kohler Crankshaft engine won't crank, begin by ensuring the PTO drive is disengaged. A discharged battery is a common culprit; charge or replace it. Also, check if the safety interlock switch is engaged and disengage it. Loose or faulty wires or connections can prevent cranking; secure them. Other potential causes include a faulty key switch or ignition switch (replace if faulty), a faulty electric starter or solenoid (replace if faulty), or seized internal engine components (inspect and repair). A blown fuse, a faulty electronic control unit, or insufficient voltage to the electronic control unit can also prevent the engine from cranking; address these issues as necessary.

What causes a Kohler Command PRO ECH650 engine to lose power?

Bradley BarberAug 28, 2025
If your Kohler Crankshaft engine is losing power, several factors could be contributing. Begin by checking the crankcase oil level; refill if low or drain if high. A dirty air cleaner element can restrict airflow; clean or replace it. Also, dirt or water in the fuel system can cause power loss; check and replace the fuel if necessary. Excessive engine load can also cause this issue; reduce the load. Other potential causes include an overheated engine (ensure proper cooling), faulty spark plugs (replace them), low compression (perform a compression test and repair), an exhaust restriction (clear any restrictions), a low battery (charge or replace it), or an incorrect governor setting (adjust the setting).

If your Kohler Crankshaft engine is overheating, several factors could be the cause. Start by checking for clogged air intake/grass screens, cooling fins, oil cooler, or cooling shrouds; clean these components to ensure proper airflow. Excessive engine load can also cause overheating; reduce the load. Check the crankcase oil level; refill if low or drain if high. A lean air-fuel mixture can also contribute to overheating; adjust the air-fuel mixture to the proper levels.

Corey LucasSep 2, 2025
If your Kohler Crankshaft engine runs but misses, several factors could be responsible. Start by checking for dirt or water in the fuel system; check and replace the fuel as necessary. Ensure the spark plug lead is connected. Poor fuel quality can also cause missing; use proper fuel quality. Other potential causes include faulty spark plugs (replace them), loose wires or connections (secure them), an overheated engine (ensure proper cooling), a faulty ignition module (replace it), an incorrect crankshaft position sensor air gap (adjust it), or insufficient voltage to the electronic control unit (ensure proper voltage supply).

Brianna NormanSep 4, 2025
If your Kohler Crankshaft engine is knocking, several factors could be the cause. Excessive engine load can cause knocking; reduce the load. Check the crankcase oil level; refill if low. Old or improper fuel can also cause knocking; use fresh and appropriate fuel. Other potential causes include internal wear or damage (inspect and repair internal engine components), hydraulic lifter malfunction (repair or replace), improper fuel quality (use proper fuel quality), or an incorrect grade of oil (use the correct grade of oil).

If your Kohler Crankshaft engine will not idle, several factors could be responsible. Start by checking for dirt or water in the fuel system; check and replace the fuel as necessary. Stale fuel or dirty fuel injectors can also cause idling issues; replace stale fuel or clean the fuel injectors. Other potential causes include faulty spark plugs (replace them), an inadequate fuel supply (ensure adequate fuel supply), low compression (perform a compression test and repair), a restricted fuel tank cap vent (clear the vent), or an overheated engine due to cooling system or air circulation problems (ensure proper cooling and air circulation).
