Use only NGK BPM-8Y spark plug (BPMR-8Y in Canada) 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.
