Why is oil leaking from the seals and gaskets on my Kohler Command CV730?
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 CV730 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 Command CV730 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 CV730 Engine 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 Command CV730 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 Command CV730 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.
What to do if my Kohler Engine cranks but will not start?
If your Kohler Engine cranks but won't start, consider these potential solutions: Ensure the battery isn't connected backward, check for a blown fuse, or examine the carburetor solenoid for malfunctions. Other possible causes include the choke not closing, a clogged fuel line or fuel filter, a failed diode in the wiring harness, or a DSAI/DSAM malfunction. Also, check for an empty fuel tank, a faulty electronic control unit or ignition coil(s), or faulty spark plug(s). The fuel pump could be malfunctioning due to a clogged or leaking vacuum hose. Ensure the fuel shut-off valve is open, the ignition module(s) are properly gapped, and there's sufficient voltage to the electronic control unit. Check the interlock and kill switches, the oil level, the fuel quality, and the SMART-SPARKTM system...
How to fix a Kohler Command CV730 Engine that cranks but won't start?
If your Kohler Engine cranks but won't start, possible causes include a backwards battery connection (correct it), a blown fuse (replace it), or a malfunctioning carburetor solenoid (repair or replace it). Other potential issues are a choke not closing (ensure proper function), a clogged fuel line or filter (clear the clog), or a failed diode in the wiring harness (replace it). Also, check for an empty fuel tank (refill it), a faulty electronic control unit (replace it), faulty ignition coils or spark plugs (replace them), a malfunctioning fuel pump (repair or replace it and check hoses), or a closed fuel shut-off valve (open it). Furthermore, inspect the ignition module(s) (fix or replace), ensure adequate voltage to the electronic control unit, check the interlock switch (repair if neede...
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 Command CV730 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.
