Adjusting idle speed
Engine stops while idling
: Open the low speed screw (L) one
full turn.
: Turn the idle speed screw (LA)
clockwise until chain begins to run –
then back it off one quarter of a turn.
Chain runs when engine is idling
: Open low speed screw (L) one full
turn.
: Turn the idle speed 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 turn)
Idle setting is too lean.
: Turn the low speed screw (L)
counterclockwise until engine
runs and accelerates smoothly.
It is usually necessary to change the
setting of the idle speed screw (LA) after
every correction to the low speed screw
(L). Readjustment of the high speed
screw (H) may be necessary in some
cases.
If engine is down on power, check the
spark arresting screen* in the muffler.
: Allow muffler to cool down
: Take out the screw (1).
: Pull the spark arresting screen (2)
out of the muffler.
: Clean spark arresting screen if
necessary.
: If the spark arresting screen is
damaged or severely coked up,
fit a new one.
: Refit the spark arresting screen –
secure it with the screw.
