9.2 The starter fixture
1.The following instructions are for increasing the service
life of the starter rope and of the starter mechanism - see
also Chapter "7 Start motor/stop motor".
Always pull the rope out in a straight line.
Do not let the rope drag across the the edge of the
rope eyelet.
Do not pull rope all the way out - risk of breaking rope.
Always follow the rope back into its start position with
your hand on the starter grip - do not let it retract on its own.
A damaged starter rope can be replaced by a specialist.

9.3 Carburetor adjustment

The carburettor is adjusted at the factory for optimum
performance. Subject to location (mountains, plains),
the carburettor may need to be adjusted.
The carburettor is equipped with 3 setting screws:
• Idle end stop, screw „T" (Pos.16)
• Idle mixture, screw „L" (Pos.17)
• Full load mixture, screw „H" (Pos.17)
The regulating screws for idle mixture
(L) and full load mixture (H) must only
be adjusted by qualified mechanics.
Minor adjustments of the idle setting to the
average idle speed stated in the specification can
be made via the idle end stop screw (T) using a
tachometer as follows:
- Turn the idle end stop screw (T) a little
anticlockwise, if the idle speed is too high.
- Turn the idle end-stop screw (T) a little clockwise,
until the motor runs smoothly, if the idle speed is
too low (in other words if the engine refuses to
start or stalls).
Ask an authorised service shop to adjust your
machine, if you cannot obtain an optimum
carburettor adjustment by correcting the idle end
stop screw „T".
The following instructions are for authorised
service shops:
Using the D-CUT carburettor:
key (SOLO part no: 00 80 537) to correct settings on
the idle mixture screw (L) and on the full load screw (H).
Using the carburettor with limitercaps:
The regulating screws for idle mix and full charge
mix can only be adjusted in a limited range.

The air filter must be clean to achieve the
correct idle adjustment. Let the engine run until
it is warm, before making any adjustments.
Maintain the values regarding the average idle
speed and maximum permissible speed stated
under "Specification".
1.The shielded sparkplug (heat rating 200) is
available under the following designation:
BOSCH WS6F
CHAMPION RCJ-6Y or comparable.
FIG. 16
2.The prescribed electrode clearance is 0.5 mm.
The sparkplug must be checked every 50 oper-
ating hours. If the electrodes are burned
down, then the sparkplug should be replaced
immediately, otherwise replace after 100
hours.
Installing and removing sparkplugs, see chap-
ter "7.4 If the motor does not start".
Only use sparkplugs with firmly mounted,
thick connecting threads on the upper end.
Otherwise there is a fire hazard through
sparking! Always firmly press the sparkplug
connector on the sparkplug.
1.Dirty air filters result in lower performance.
They increase fuel consumption, and thus
increase the pollutants in the exhaust. In addi-
tion, starting will be more difficult.
2.Execute the following maintenance work
regularly.
Before opening the air filter, close the starter
shutter (
carburetor.
Press in the clip (1) and tilt the filter housing
(2) back and remove. Clean around the filter.
Please note:
The carburettor is adjusted to
achieve maximum engine power.
Always use a tachometer to carry
out this adjustment.
