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 des-
ignated 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.
■ Adjusting the engine
Although the engine is adjusted on leaving the factory,
after repeated use it may sometimes require readjust-
ment or maintenance. Please consult your original sup-
plier regarding inspections and maintenance other than
those shown below.

• Throttle wire play
Throttle wire play should be 1 to 2 mm. After com-
pletely 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 tightening the lock nut.
