Level 2.
Parts Required: None.
IMPORTANT
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 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 throttle cable end from the carburetor swivel.
2. Remove four screws from starter cover, lift the cover from the
engine and lay to the side.
NOTE
The throttle cable remains assembled to the cover.
