Carburetor
1 High speed adjustment screw
2 Low speed adjustment screw
3 Idle speed regulating screw
The carburetor has been adjusted at the factory for maxi-
mum performance and lowest fuel consumption under
local average atmospheric conditions.
When working at high altitudes (mountains) or near sea
level the carburetor must be readjusted. The adjustment
must be made at the two adjustment screws and at
the
idle speed regulating screw.
For the basic adjustment- it should be taken as a guide for
all readjustments
- both adjustment screws are screwed
in carefully until they have a snug fit. Thereafter the
following adjustments have
to be made:
High speed adjustment screw H: open 1114 of a turn
Low speed adjustment screw L: open 1of a turn
Never interchange the adjustment screws!
Carburetor adjustment must only be done while engine is
warm and with clean air filter.
Regulating the idle speed regulating screw
Hints for readjustment of the carburetor
Engine stalls at idle speed:
With engine running turn idle speed adjusting screw
slighHy to the right - clockwise - (chain must not
run).
Chain runs when engine is idling:
Turn idle speed adjustment screw slightly to the left anti-
clockwise.
Engine speed erratic when idling:
Adjust low speed adjustment screw. You get a leaner mix-
ture by turning it to the right - clockwise - and a richer mix-
ture by turning it anti-clockwise.
Except for simple maintenance works repairs should be
done
by an authorized STIHL service shop. In many places
you find service shops with
al necessary tools and trained
personell.
