Troubleshooting the engine on your Kohler generator when the engine runs rough

If your generator engine cuts out, smokes, idles poorly, vibrates or runs erratically, it could need a good tune-up to replace the spark plug, oil and air filter. Or the problem could be with the generator engine's fuel system. Rebuild or replace the carburetor if the engine isn't getting a good supply of fuel.

If the engine misfires, backfires, sputters or jerks the starter rope out of your hand when you try to start it, the flywheel key could be broken. A broken flywheel key disrupts the ignition timing because the magnets aren't passing the ignition coil in synchronization with piston movement. Replace the flywheel key if it's damaged or broken.

Common Kohler generator replacement parts

• Carburetor. The carburetor mixes air and gas before the fuel mix goes to the engine.
• Digital spark advance module. The digital spark advance module optimizes engine performance by precisely controlling spark timing.
• Brush holder and rectifier assembly. The brush holder and rectifier assembly creates and delivers DC voltage to the rotor to create a stronger magnetic field, increasing and maintaining the AC voltage output.
• Circuit breaker. The circuit breaker stops the flow of electricity in the generator if an overload or short circuit occurs.
