NOTE
Operating on Highlands
On highlands, the standard carburetor air/
fuel mixture is relatively too rich so the
engine performance may be impaired while
the fuel consumption may increase.
High altitude performance can be improved
by installing a smaller diameter main fuel
jet in the carburetor, and readjusting the
idle needle screw and the idle adjust screw.
If you always operate the engine at altitudes
higher than 1830m above sea level, ask your
dealer for adjusting the carburetor.
The engine power will decrease
approximately 3.5% for every 305 meters
increase in altitude, even the proper main jet

on power will be greater than this if no
carburetor modification is conducted.
CAUTION
The engine equipped with the main jet
applicable to highlands may be damaged
seriously in area below specified altitude,
because its mixture ratio is too lean, output
drops and the engine overheats for operation
in low altitude area. In the case, ask your
dealer to recover the engine to its normal
technical status.
STOPPING THE ENGINE
In an emergency, push the engine switch to
“OFF” to stall the engine. Stop it in normal in the
following sequence:
1. Push up the throttle lever to the SLOW
position (Fig. 10).

I. MAINTENANCE SCHEDULE
Periodic inspection and adjustment of the
engine is essential if high level performance is
to be maintained. Regular maintenance will also
ensure a long service life. The required service
