bending outer electrode.
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.
