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 com-
bustion heat away from the engine.
Overheating and engine seizure can occur when:
• Air intakes in the crankcase 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 crankcase cooling passage blockages or cleaning of cooling
fins is considered “Normal Maintenance.” Any failure attributed to lack
of maintenance is not warranted.
