A spark ignition internal combustion engine is described including a throttle valve, an exhaust valve movable between a substantially closed portion affording minimum exhaust gas flow and a substantially open position affording maximum exhaust gas flow, a spark timing device, and a control mechanism comprising a pivot on the engine, a control member pivotally carried on the pivot, a throttle control linkage connected to the control member and to the throttle valve for controlling the throttle valve in response to pivotal movement of the control member, an exhaust control linkage connecting the control member to the exhaust valve for controlling exhaust valve movement between the open and closed positions in response to pivotal movement of the control member and a spark timing control linkage connecting the control member to the spark timing device for control of the spark timing device in response to pivotal movement of the control member. The spark timing control linkage includes a translatorily movable link connected between the control member and the spark timing device, whereby to provide for coordinated control of the throttle valve, and exhaust valve, and the spark timing device.
