ABSTRACT:
A manual positioning system for the metering valve and variable geometry actuator of a fuel control has a pair of drive shafts which have engagement structures mounted respectively on their ends for drivingly engaging the metering valve and the cam of the variable geometry actuator. The drive shafts carry gears which are in meshing engagement with a gear carried by a speed setting lever member. Upon the application of a manual control signal, the engagement structures respectively engage the metering valve and the cam such that the lever member may subsequently position these elements.
