MAINTENANCE
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. Close choke (COLD START
[ ] position). This prevents
dirt from entering the
carburetor throat when the air
filter is removed. Remove air
cleaner cover (A).
3. Remove engine cover (B).
DO NOT use a metal scraper to remove dirt from the cylinder fins.
