NOTE
In a disassembled carburetor, the position of the jet needle (pos. 3) can be
changed. The standard position of the jet needle is 'position 2'. If the clip (pos. 4)
is set in 'position 1' of the jet needle, the full mixture in part and full-load will be-
come slightly leaner. If the clip (pos. 4) is set into 'position 5', the fuel mixture will
become slightly richer in the part and full-load range.
NOTE
The fuel filter (pos. 32) is located below the fuel inlet on the carburetor, preventing
contamination from entering the carburetor, which could impair operation of the
carburetor.
NOTE
When trying to start the engine it, will take a few seconds for the fuel pump to fill
the float chamber and for the engine to start.
NOTE
With the adjustment screw (pos. 36), the idle speed of the engine can be ad-
justed. By turning in the adjustment screw (pos. 36) the idle speed increases and
by turning out the screw (pos. 36) the idle speed will be reduced.
NOTE
With the adjustment screw (pos. 31), the fuel mixture formation can be adjusted.
By turning in the adjustment screw (pos. 31), the air-fuel mixture will become rich-
er at idling and by turning out the screw (pos. 31), the air-fuel mixture will become
leaner at idling. The default setting of the adjustment screw are two full turns and
one quarter of a turn (2 ¼) from inside to outside.
