Version B: Fine Tuning A slight correction of the setting of the high speed screw (H) may be necessary if engine power is not satisfactory when operating at high altitude, sea level or after changing the working tool. Rule of thumb: Turn the high speed screw (H) about one quarter turn for every 1000m (3300 ft) change in altitude. 20 KM 110 R, KM 130 R

Version B
–
High speed screw and low speed
screw with slotted head.
With this carburetor it is only possible to
adjust the high speed and low speed
screws within fine limits.
Standard Setting
N
Stopping the Engine
N
Mount the KombiTool complete with
working tool or cutting attachment.
N
Check the air filter and clean or
replace as necessary.
N
Check that the throttle cable is
properly adjusted – readjust if
necessary – see chapter on
"Adjusting the Throttle Cable".
N
Check the spark arresting screen
(not in all versions) and clean or
replace as necessary.
N
Carefully turn both adjusting screws
counterclockwise as far as stop:
–
The high speed screw (H) is 3/4 turn
open.
–
The low speed screw (L) is 3/4 turn
open.
N
Start and warm up the engine.
N
Adjust idle speed with the idle speed
screw (LA) so that the cutting
attachment does not move.
Adjusting Idle Speed
It is usually necessary to change the
setting of the idle speed screw (LA) after
every correction to the low speed screw
(L).
N
Warm up the engine for about 3
minutes.
Engine stops while idling
N
Turn the idle speed screw (LA)
slowly clockwise until the engine
runs smoothly – the cutting
attachment must not move.
Cutting attachment runs when engine is
idling
N
Turn the idle speed screw (LA)
counterclockwise until the cutting
attachment stops running and then
turn the screw about another 1/2 to
3/4 turn in the same direction.
If the working tool or cutting attachment
continues to run when the engine is
idling, have your machine checked and
repaired by your servicing dealer.
Erratic idling behavior, engine stops
even though setting of LA
-
screw has
been corrected, poor acceleration
Idle setting is too lean:
N
Turn the low speed screw (L)
counterclockwise, no further than
stop, until the engine runs and
accelerates smoothly.
Erratic idling behavior
Idle setting is too rich
N
Turn the low speed screw (L)
clockwise, no further than stop, until
the engine runs and accelerates
smoothly.
Version B: Fine Tuning
A slight correction of the setting of the
high speed screw (H) may be necessary
if engine power is not satisfactory when
operating at high altitude, sea level or
after changing the working tool.
Rule of thumb:
Turn the high speed screw (H) about
one quarter turn for every 1000m (3300
ft) change in altitude.
