Why is my Kohler Engine knocking?
If your Kohler Engine is knocking, several factors could be the cause. Here's what to check: * Reduce excessive engine load. * Add oil to the appropriate level if the crankcase oil level is low. * Replace with fresh, clean fuel. * Use the correct oil viscosity/type. Additionally, investigate and remedy any internal wear or damage and replace the faulty hydraulic lifter.
Why is my Kohler Engine leaking oil from oil seals and gaskets?
If you notice oil leaks from the oil seals and gaskets of your Kohler Engine, the following could be the reasons: * Replace the broken breather reed. * Repair or replace the crankcase breather. * Clear the restricted exhaust. * Tighten fasteners to the correct torque. * Repair or replace the leaky components.
Why Kohler Command CH25 cranks but won't start?
If your Kohler Engine cranks but refuses to start, several factors could be at play. It could be due to a battery connected backwards, a blown fuse, a malfunctioning carburetor solenoid, the choke not closing properly, or a clogged fuel line or fuel filter. Other potential causes include a failed diode in the wiring harness, a DSAI or DSAM malfunction, an empty fuel tank, a faulty electronic control unit, faulty ignition coils or spark plugs, a fuel pump malfunction with a clogged or leaking vacuum hose, a closed fuel shut-off valve, faulty or improperly gapped ignition modules, insufficient voltage to the electronic control unit, an engaged or faulty interlock switch, the key or kill switch in the OFF position, a low oil level, poor fuel quality, a SMART-SPARK malfunction, or disconnected...
