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 covered by the warranty.
