Adjustment for operation at high
altitude or at sea level
A slight correction of the setting may be
necessary if engine power is not
satisfactory when operating at high
altitude or at sea level:
:
Check the air filter and clean it if
necessary.
:
Warm up the engine.
At high altitude
:
Rotate the high speed adjusting
screw (H) clockwise (leaner) – no
further than stop.
At sea level
:
Rotate the high speed adjusting
screw (H) counterclockwise (richer)
no further than stop.

Adjusting idle speed
Engine stops while idling
:
Open the low speed screw (L)
counterclockwise one quarter of a
turn from max. lean setting.
:
Turn the idle speed adjusting screw
(LA) clockwise until chain begins to
run – then back off the screw one
quarter of a turn.
Chain runs when engine is idling
:
Open the low speed screw (L)
counterclockwise one quarter of a
turn from max. lean setting.
:
Turn the idle speed adjusting screw
(LA) counterclockwise until chain
stops running – then turn screw
another quarter turn in the same
direction.
Erratic idling behavior, poor
acceleration
(even though you have opened low
speed screw one quarter of a turn)
Idle setting is too lean.
:
Turn the low speed adjusting screw
(L) counterclockwise until engine
runs and accelerates smoothly.
It is usually necessary to change the
setting of the idle speed adjusting screw
(LA) after every correction to the low
speed adjusting screw (L).
