4. The proper spark plug for this engine is NGK BPMR7A. The
firing gap between the electrodes should be adjusted to 0.65
mm (0.026 in) before use.
5. Install the spark plug. Proper tightness with a cold engine is
17 to 19 N•m (170 to 190 kgf•cm).
6. Many failed plugs can be restored by filing or scraping the
electrodes down to bare metal, cleaning all deposits off the
porcelain insulation around the centre electrode, then re-
gapping.
Fuel vapours are extremely flammable and may cause
fire and/or explosion. Never test for ignition spark by
grounding spark plug near cylinder plug hole, other-
wise serious personal injury may result.

Adjusting the Belt

Adjust the belt if it becomes loose.
1. Loosen the 2 arm mounting bolts about 1 turn.
2. Turn the tension screw so the washer lines up with the mark
on the clutch cover.
3. Tighten the 2 arm mounting bolts. Note: Tighten to a torque
of 23 to 27N•m (230 to 270 kgf•cm).

Replacing the Belt

Replace the belt when it becomes very worn.
