IMPORTANT
• If too much fuel is absorbed or poor quality oil is used,
the spark plug electrodes become dirty, making the
engine harder to start.
• Note that using any spark plug other than those
designated may result in the engine failing to operate
properly or in the engine becoming overheated and
damaged.
• To install the spark plug, first turn the plug until it is
finger tight, then tighten it a quarter turn more with a
socket wrench.

Throttle wire play
Throttle wire play should be 1 to 2 mm. After completely
returning the throttle lever, take the throttle wire at the
carburetor end in your fingers and give a light tug. If
the play is too great or too small, readjust the position
of the wire retaining nut. Loosen the lock nut and turn
the wire retaining nut clockwise (screw in) to increase
the play and counter-clockwise (unscrew) to reduce it.
After adjusting, please fasten the wire retaining nut by

WARNING
• Inspect periodically, the muffler for loose fasteners,
any damage or corrosion. If any sign of exhaust

and wipe away any carbon buildup. Wipe away any
carbon buildup on the muffler exhaust vent and cylinder
exhaust port at the same time.
2. Tighten all screws, bolts, and fittings.

between the clutch lining and drum, and if it has, wipe
it away using oil-free, lead-free gasoline.
