Spark Plug

Level 2.

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.

1. Remove spark plug lead.
