Carburetor adjustment (Fig. 3-1, 1 B)
WARNING! The bit may be spinning during carburetor adjustments.
WARNING! Never start the engine without the complete clutch cover and gear case assembled! Otherwise
the clutch can come loose and cause personal injuries.
In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is basically
adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one
adjustment possibility:
T = Idle speed adjustment screw.
Idle speed adjustment (T)
Check that the air filter is clean. When the idle speed is correct, the bit will not rotate. If adjustment is required,
close (clockwise) the T-screw, with the engine running, until the bit starts to rotate. Open (counter-clockwise) the
screw until the bit stops. You have reached the correct idle speed when the engine runs smoothly in all positions
well below the rpm when the bit starts to rotate.
If the bit still rotates after idle speed adjustment, contact your service workshop.
NOTE! The standard openings (returns) of L/H screws from lightly seated positions are as follows.
This setting is the WA-type carburetor only when the unit is installed.
WARNING! When the engine is idling the bit must under no circumstances rotate.

model, which carry the following label on the unit are different from the
ones for other market in carburetor adjustment. Adjustment of Standard
