cooling system

Level 2.

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 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.

1.Remove spark plug lead.

2.Remove air cleaner cover.

3.Remove (2) muffler cover screws and muffler cover (A).

4.Remove (2) engine cover screws and engine cover (B).
