( c )                  Setting up the Control Cam
          
                        Illustration LSK405 shows the assembly and application of the
                        control lever to the metering unit. Initial settings are
                        obtained by the use of shims between the mating flanges,
                        while an eccentric pivot pin provides limited adjustment -
                        both rich and lean - about the datum fuel setting chosen.

                        The pins shown at "A" and "B" can be used as cam positioning
                         stops for setting-up purposes,  but they should not be used as
                         throttle limiting stops.

                        The shape of the control lever can be varied to suit the particular
                        engine and throttle configuration.  For this reason, this component
                        is not supplied as part of the equipment but is left to the engine
                        manufacturer to make to suit the requirements.  Illustration
                        LSK391 shows nominal dimensions of a form of control lever.
