Wheel Horse lawn mower replacement parts include air and fuel filters, ignition coils, carburetor bowls and flywheel keys. Other replacement parts include spark plugs and spark plug boots, float needles and starter gears.
If a Wheel Horse lawn mower fails to start or runs rough, a burned-out or damaged spark plug is often to blame. Suspect a broken flywheel key if the mower stops running after hitting a hard object. If a mower does not start after a long time in storage, the float needle is potentially stuck. Replacing the carburetor bowl or gaskets often stop leaks in the mower's carburetor.
