Spark Plug
Level 2.
Use only NGK BPM-7A spark plug (BPMR-7A 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.
1. Remove throttle cable end from the carburetor swivel.
2. Remove the four screws that retain the engine cover. Two at the top of the starter, two on either side of
the front. Lift the cover from the engine and lay to the front of the pump.
Note: The throttle cable remains assembled to the engine cover and the spark plug lead and grommet
remain installed.
DO NOT use a metal scraper to remove dirt from the cylinder fins.
