13.1.2.9) Check of float needle valve
See Pic. 70 and 71.
Drive out peg Q with a pin punch and remove float suspension W
and float needle.

flow.

clip into float bracket, place it in position and fix float bracket with
pin.
Fit float chamber and fix it with plug screw Q and sealing ring 16/
22/1. Apply safety wiring.
