-1

• If it is necessary to change the rotation speed, regulate the adjusting

screw, with Phillips screwdriver.

• Turn the adjusting screw to the right, and the engine rotation will

increase. Turn the adjusting screw to the left, and the engine rotation

will drop.

NOTE

• The engine may be damaged if the choke lever is moved further beyond the “CLOSE” position.
• If the engine stops with an explosion sound or if the engine started, but stopped before operation of the choke lever, return this lever to

the “OPEN” position and pull the starter handle several times to start the engine again.

• If the operator keeps pulling the starter handle several times with the choke lever left in the “CLOSE” position, the engine may be difficult

to start because of over-suction of the fuel.

• In case of over-suction of the fuel, remove the spark plug and pull the handle several times rapidly to discharge any excess fuel. Dry the

spark plug electrode.

• When the throttle valve does not return to a position in contact with the idling adjusting screw even if the throttle lever is set to the low

speed, correct the control cable catching state to ensure proper return of the valve.
