2. To take the needle valve (is not subject to repeated installation).

Prevention

It is impossible to unscrew bolts of fastening of the elements which are dosing out fuel, with a view of simplification of access to a float.


3. To establish the new needle valve and a new clip, paying attention to the correct placement of a clip in the flute of the valve provided for it.
4. To insert a float, paying attention to the correct provision of remote laying between the holder of the lever and the needle valve, and to insert an axis into cut of the holder of a float.
5. Several times to move a float, checking possibility of its free rotation on an axis.
