Cooling System

Level 2.

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 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 considered “Normal

Maintenance.” Any failure attributed

to lack of maintenance is not warranted.
