Why is oil leaking from the seals and gaskets on my Kohler Command CV750?
If oil leaks from the oil seals and gaskets of your Kohler Engine, check for a broken breather reed or a clogged, broken, or inoperative crankcase breather. Also, inspect for loose or improperly torqued fasteners, piston blow-by or leaky valves, or a restricted exhaust.
Why does my Kohler Command CV750 Engine use an excessive amount of oil?
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 so hard to start?
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.
What to do if Kohler Command CV750 starts but does not keep running?
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.
Why does my Kohler Engine run but misses?
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.
Why is my Kohler Engine using an excessive amount of oil?
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 is my Kohler Command CV750 Engine leaking oil from oil seals and gaskets?
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).
What causes a Kohler Command CV750 to overheat?
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 knock?
If your Kohler Engine knocks, consider these potential causes: excessive engine load, hydraulic lifter malfunction, incorrect oil viscosity/type, internal wear or damage, low crankcase oil level, or poor fuel quality.
Why is my Kohler Engine overheating?
If your Kohler Engine overheats, check for a broken cooling fan, excessive engine load, or a failed fan belt. A faulty carburetor, high or low crankcase oil level, or a lean fuel mixture could also be the cause. Additionally, inspect the cooling system fluid level and the radiator for clogs, restrictions, or leaks. Other possible issues include a failed water pump belt or a malfunctioning water pump.
