Spark Arresting Screen In Muffler - Stihl MS 460 Instruction Manual

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).
Fine Tuning for Operation at High
Altitude
A slight correction of the setting may be
necessary if engine power is not
satisfactory when operating at high
altitude:
: Check the standard setting.
: Warm up the engine.
: Turn high speed screw (H) slightly
clockwise (leaner). On models with
3
H = / , turn no further than stop.

If the setting is too lean there is
a risk of engine damage due to
insufficient lubrication and
overheating.
