■ IDLE ADJUSTMENT SCREW
This is the screw to adjust the engine
rotation when the throttle lever is set
to the idling position. If you turn right
(clockwise), rotation increases, and
left (counterclockwise) decreases.
In case the blade continues to rotate
or engine stops when you return the
throttle lever completely to the idling
position, make readjustment.
■ FUEL ADJUSTMENT SCREW
The fuel adjustment screw is
adjusted at the time of shipment.
Ordinary there is no need to
adjustment, but in case acceleration
becomes bad or fuel consumption
increases cause of conditional
change, adjust the fuel adjustment
screw as follows.
Stop the engine. Turn the screw at
standard open degree and restart the
engine. Adjust the screw within
permission range. (Blade does not
rotate and engine. stabilize in idling
position, and acceleration is good if
the adjustment is succeeded.)
Standard open degree: 1 turn return
Permission range: ±1/4 turns
