Abstract: A manually operable control is provided for effecting acceleration and deceleration of an engine by selective actuation of an engine fuel control device. The control includes an output section comprising first, second and third arms mounted for pivoting about a common axis. A hand throttle linkage is connected directly to the first arm for swinging the latter among selected angular positions and for fixing the first arm in said positions. A foot throttle linkage is connected directly to the second arm, which in turn is connected to the fuel control device. The first and second arms are located on opposite sides of the third arm and have respective abutment portions which extend axially towards the third arm and are disposed so as to respectively be in the paths of movement of a pair of oppositely extending abutment portions of the third arm.
