Setting the fuel level in the carburetor float chamber
1 – carburetor cover; 2 – needle valve seat; 3 – emphasis; 4 – needle valve; 5 – ball of the shut-off needle; 6 – valve needle pull-off fork; 7 – float bracket; 8 – tongue; 9 – float; 10 – gasket
The fuel level required for normal operation of the carburetor is ensured by the correct installation of serviceable elements of the shut-off device.
The distance between the float and gasket 10 adjacent to the carburetor cover (dimension A) should be 6.5±0.25 mm; this size is adjusted by bending the tongue 8. In this case, the supporting surface of the tongue should be perpendicular to the axis of the needle valve and should not have any nicks or dents.
Perform the check using caliber 67.8151.9505. Hold the housing cover vertically so that the tongue 8 of the float lightly touches the ball 5 of the needle valve 4, without pressing it down.
Adjust the maximum float stroke of 8±0.25 mm by bending stop 3. The tension fork 6 of the valve needle should not impede the free movement of the float.
When installing the carburetor cover, check that the float does not touch the walls of the float chamber.

Caution: Always check the float setting when replacing the float or needle valve; in the latter case, it is also necessary to replace the valve sealing gasket.
