Parts Required: None if you are careful.

IMPORTANT

To maintain proper engine operating temperatures, cooling air

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

carries combustion heat away from the engine.

Overheating and engine seizure can occur when:

• Air intakes are blocked, preventing cooling air from reaching the cyl-

inder.

• 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 cooling passage blockages or cleaning of cooling fins is

considered “Normal Maintenance.” Any failure attributed to lack of

maintenance is not warranted.
