SLOW FAST
CONTROL LEVER
Operate the recoil starter as soon as you move the flywheel
brake lever to the RELEASED position. The choke lever
automatically begins moving to the OPEN position when the
flywheel brake lever is moved to the RELEASED position.
If the engine does not start within several consecutive pulls of
the recoil starter, move the flywheel brake lever to the
ENGAGED position and move the choke lever to the CLOSE
position.
Move the flywheel brake lever to the RELEASED position and
immediately begin operating the recoil starter.
When engine warms up, move the control lever to FAST or
SLOW.

High altitude operation
Operation of the engine at an altitude lower than the carburetor is
jetted for may result in reduced performance, overheating, and
serious engine damage caused by an excessively lean air/fuel
mixture.
At high altitude, the standard carburetor air-fuel mixture will be ex-
cessively rich. Performance will decrease, and fuel consumption
will increase.
Even with suitable carburetor jetting, engine horsepower will
decrease approximately 3.5% for each 300 m (1,000 feet) increase
in altitude. The effect of altitude on the horsepower will be greater
than this if no carburetor modification is made.
High altitude performance can be improved by specific modifica-
tions to the carburetor. If you always operate the engine at
altitudes higher than 1,500 m (5,000 feet) above sea level, have
your authorized Honda dealer perform these carburetor modifi-
cations.
