To maintain proper engine operating temperatures, cooling air 

must pass freely through the cylinder fin area. This flow of air car-

ries combustion heat away from the engine.

Overheating and engine seizure can occur when:

•  Air intakes in the crankcase are blocked, preventing cooling air from 

reaching the cylinder.

•  Dust and grass build up on the outside of the cylinder. This build up  

insulates the engine and prevents the heat from leaving.

Removal of crankcase cooling passage blockages or cleaning of cooling 

fins is considered “Normal Maintenance.” Any failure attributed to lack 

of maintenance is not warranted.
