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 spark plug lead.
2.  Remove air cleaner cover (A).
3.  Remove 2 engine cover screws and engine cover (B).
