and in the lever arm groove. (E)
Check the lever arm for damage to the groove (F)
for the needle valve and wear on the mounting
points towards the control diaphragm (G).
Replace damaged components with new ones.
Remove the bolt holding the cover over the pump
diaphragm.
Lift off the cover (H), the gasket (J) and the dia-
phragm (K).

needle for example. Clean or replace the fuel
