Cooling System

Level 2.

To maintain proper engine oper-

ating temperatures, cooling air

must pass freely through the cyl-

inder fin area. This flow of air car-

ries combustion heat away from

the engine.

Overheating and engine seizure can

occur when:

• Air intakes are blocked, prevent-

ing 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 cooling passage blockages or cleaning of cooling fins is consid-

ered “Normal Maintenance.” Any failure attributed to lack of maintenance is

not warranted.

Parts Required: None if you are careful.
