A mixture ratio control having a pair of valve arms attached to a rigid triangular-shaped member. A mixture ratio control actuator and a throttle actuator are also attached to the rigid member. Movement of the mixture ratio control actuator determines the vertical position of the pair of valve arms and therefore determines the flow through a pair of valves utilized in conjunction with the valve arms. After a setting of the mixture ratio control actuator, any subsequent movement of the throttle actuator moves the valve arms in a substantially straight line. Furthermore, throughout the entire throttle stroke the mixture ratio percentage flow through the valves remain constant.
