Why does my Kohler Command CV22 start but not keep running?
- M
  Melissa RodriguezAug 20, 2025
  If your Kohler Engine starts but doesn't keep running, the issue might be a faulty carburetor (replace it) or a faulty cylinder head gasket (replace it). Also, check for misadjusted choke or throttle controls (adjust or repair), a fuel pump malfunction (repair or replace the fuel pump), or an intake system leak (repair the leak). Loose wires intermittently grounding the ignition kill circuit can also cause this issue (secure loose wires and connections). Ensure you are using fresh, quality fuel and that the fuel tank cap vent isn't restricted (clear the vent restriction).

Why does my Kohler Command CV22 use an excessive amount of oil?
- J
  James RiveraAug 22, 2025
  If your Kohler Engine uses an excessive amount of oil, it could be due to loose or improperly torqued fasteners (tighten them), a blown head gasket or overheating (replace the head gasket), or a broken breather reed (replace it). Other possible causes include a clogged, broken, or inoperative crankcase breather (repair or replace it), an overfilled crankcase (drain excess oil), or using the incorrect oil viscosity or type (use the correct one). Additionally, worn cylinder bore (repair or replace), worn or broken piston rings (repair or replace), or worn valve stems or guides (repair or replace) can contribute to excessive oil consumption.

Why is my Kohler Engine losing power?
- C
  Chad Hill MDAug 26, 2025
  If your Kohler Engine loses power, it could be due to a dirty air cleaner element (clean or replace it), overheating (address the issue), or excessive engine load (reduce the load). Other possible causes include a restricted exhaust (clear it), faulty spark plugs (replace them), high crankcase oil level (reduce it), or an incorrect governor setting (adjust it). Furthermore, a low battery (recharge or replace it), low compression (perform a compression test and repair), low crankcase oil level (add oil), or poor fuel quality (replace with fresh fuel) can also be responsible.

Why does my Kohler Command CV22 start hard?
- J
  Jennifer ThompsonAug 28, 2025
  If your Kohler Engine starts hard, it could be due to a clogged fuel line or filter (clear it). Other potential causes include engine overheating (address the issue), a faulty ACR mechanism (repair it), or misadjusted choke or throttle controls (adjust or repair them). Also, check for faulty spark plugs (replace them), a sheared flywheel key (replace it), or a fuel pump malfunction (repair or replace the pump). Additionally, an engaged or faulty interlock switch (check and repair if needed), loose wires grounding the ignition kill circuit (secure them), low compression (perform a test and repair), or poor fuel quality (replace with fresh fuel) can contribute to hard starting, as well as weak spark (address the weak spark issue).

What to do if Kohler Command CV22 will not crank?
- M
  Michael BaileyAug 30, 2025
  If your Kohler Engine will not crank, the battery might be discharged (recharge or replace it). Other possible causes include a faulty electric starter or solenoid (replace them), faulty key or ignition switch (replace them), or an engaged or faulty interlock switch (check and repair if needed). Additionally, loose wires grounding the ignition kill circuit (secure them), pawls not engaging in the drive cup (repair or replace pawls), or seized internal engine components (repair them) can prevent the engine from cranking.

What causes a Kohler Command CV22 to overheat?
- E
  Emma HernandezSep 2, 2025
  If your Kohler Engine overheats, possible causes include a broken cooling fan (repair or replace it), excessive engine load (reduce it), or a failed or off fan belt (replace or adjust it). A faulty carburetor (replace it), high or low crankcase oil level (adjust to correct level), or a lean fuel mixture (adjust the fuel mixture) can also cause overheating. Other potential issues are low cooling system fluid level (refill it), clogged radiator or cooling system components (clean or repair), a failed or broken water pump belt (replace it), or a malfunctioning water pump (repair or replace it).

What causes a Kohler Engine to run but miss?
- G
  Gerald AdamsSep 5, 2025
  If your Kohler Engine runs but misses, the carburetor might be adjusted incorrectly (correct the adjustment). Other potential causes include engine overheating (address the issue), faulty spark plugs (replace them), or faulty or improperly gapped ignition modules (fix or replace them). Additionally, check for an incorrect crankshaft position sensor air gap (adjust it), an engaged or faulty interlock switch (check and repair if needed), loose wires grounding the ignition kill circuit (secure them), or poor fuel quality (replace with fresh fuel). Also, ensure spark plug leads are connected and tight.

What causes a Kohler Command CV22 to knock?
- E
  Erik LongSep 7, 2025
  If your Kohler Engine knocks, it may be due to excessive engine load (reduce it), a hydraulic lifter malfunction (repair or replace it), or using the incorrect oil viscosity or type (use the correct one). Internal wear or damage (repair or replace worn components), low crankcase oil level (add oil to the correct level), or poor fuel quality (replace with fresh, quality fuel) can also cause knocking.

Why won't my Kohler Command CV22 Engine idle?
- C
  Cindy JohnsonSep 12, 2025
  If your Kohler Engine will not idle, it could be due to engine overheating (address the issue) or faulty spark plugs (replace them). Other possible causes include improperly set idle fuel adjusting needles (adjust them) or idle speed adjusting screw (adjust it). Also, check for inadequate fuel supply (ensure adequate supply), low compression (perform a test and repair), poor fuel quality (replace with fresh fuel), or a restricted fuel tank cap vent (clear the restriction).

Why is my Kohler Command CV22 Engine leaking oil from oil seals and gaskets?
- T
  Thomas StanleySep 13, 2025
  If oil leaks from the oil seals and gaskets of your Kohler Engine, it could be due to a broken breather reed (replace it) or a clogged, broken, or inoperative crankcase breather (repair or replace it). Other potential causes include loose or improperly torqued fasteners (tighten them), piston blow by or leaky valves (repair or replace leaky valve parts), or a restricted exhaust (clear the exhaust restriction).
