Why does my Kohler Engine start hard?

  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).

Why is my Kohler Engine losing power?

  Heather BlankenshipSep 3, 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 is my Kohler Engine using an excessive amount of oil?

  Jennifer MartinSep 1, 2025
  If your Kohler Engine uses an excessive amount of oil, check for loose or improperly torqued fasteners, a blown head gasket (possibly due to overheating), or a broken breather reed. Other potential causes include a clogged, broken, or inoperative crankcase breather, an overfilled crankcase, or incorrect oil viscosity/type. Worn cylinder bore, piston rings, or valve stems/guides could also be the reason.

Why does my Kohler Engine run but misses?
- K
  Kevin JohnsonAug 31, 2025
  If your Kohler Engine runs but misses, it could be due to an incorrectly adjusted carburetor, an overheated engine, or faulty spark plugs. Other potential causes include faulty or improperly gapped ignition module(s), an incorrect crankshaft position sensor air gap, or an engaged or faulty interlock switch. Loose wires grounding the ignition kill circuit, poor fuel quality, or disconnected or loose spark plug leads could also be to blame.

  Jeanne BrownAug 29, 2025
  If your Kohler Engine starts but doesn't keep running, a faulty carburetor or cylinder head gasket could be the issue. Also, check for faulty or misadjusted choke or throttle controls, a malfunctioning fuel pump with a clogged or leaking vacuum hose, or an intake system leak. Loose wires intermittently grounding the ignition kill circuit, poor fuel quality, or a restricted fuel tank cap vent might also be to blame.

  If your Kohler Engine starts hard, you might have a clogged fuel line or fuel filter. Other potential causes include an overheated engine, a faulty ACR mechanism, or misadjusted choke or throttle controls. Also, check for faulty spark plugs, a sheared flywheel key, or a malfunctioning fuel pump with a clogged or leaking vacuum hose. An engaged or faulty interlock switch, loose wires grounding the ignition kill circuit, low compression, or poor fuel quality could also be to blame. Finally, consider a weak spark as a possibility.

Why does my Kohler Command CV25 use an excessive amount of oil?
- C
  Cheryl SimmonsAug 27, 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.
