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 (A).
3. Remove engine cover (B).
DO NOT use a metal scraper to remove dirt from the cylinder fins.
