2) When the engine is warm

(1) Place the engine on a flat ground.
(2) Press the primary pump several times.
(3) Confirm that the choke lever is open.
(4) Hold the main handle with left hand to prevent the engine from moving.
(5) Pull out slowly the starter handle till a certain resistance is felt. Return the starter handle backward once from this position, then pull it

out with force.

(6) When the engine is difficult to start, open the throttle valve by about 1/3.

2. Stopping

1) When the cruise control lever is OFF

Release the trigger lever to reduce the engine speed, and set the
stop switch to the “O” position.

2) When the cruise control lever is ON

Set the cruise control lever to the OFF position, reduce the engine
speed, and set the stop switch to the “O” position.

ADJUSTMENT OF IDLING

Checkup of low-speed rotation

Set the low-speed rotation to 3500 rpm (min

–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 speed will

increase. Turn the adjusting screw to the left, and the engine speed will
drop.

NOTE

• The engine may be damaged if the choke lever is moved further beyond the “CLOSE” position.

• If the engine fires and stops, 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 flooding of the fuel.

• In case of flooding 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.

DANGER

The carburetor is factory adjusted. Please do not adjust other than idling adjusting. When adjustment becomes necessary, please consult your
dealership or an authorized service agent.
