4. Tighten spark plug to 150-170 kgf • cm (130-150 in • lbf).
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 warranted.
