TEST

    REMOVE the air filter cover-plate from the control unit, after removing the four retaining screws, below this will be seen the cover-plate
    which is retained by three screws. When this is removed, the linkage is exposed.

(ii) CHECK that the overfuel lever in the control unit moves in accordance with the starting lever on the dashboard.

 the overfuel lever throughout its excess fuel range.
