Spark Plug
Level 2.
Use only NGK BPMR-8Y otherwise severe engine damage may
occur.
1. Remove spark plug and check
for fouling, worn and rounded
center electrode.
2. Clean the plug or replace with
a new one. DO NOT sand blast
to clean. Remaining sand will
damage engine.
3. Adjust spark plug gap by
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.
Removal of cooling passage blockages or cleaning of cooling fins is
considered “Normal Maintenance.” Any failure attributed to lack of
maintenance is not warranted.
