ABSTRACT:
An actuator is for a vehicle engine including a carburetor having a throttle plate moveable between a minimum open position and a maximum open position. The actuator includes an input member movably coupled with the vehicle so as to be displaceable between an initial position and a maximum displaced position. A flexible connector has a first end connected with the input member and a second end connected with the throttle plate such that movement of the input member displaces the connector to move the throttle plate between the minimum and maximum positions. A guide is configured to direct movement of the connector such that a rate of displacement of the throttle plate is varied as the input member moves between the initial and maximum positions. Preferably, the guide includes two curved guide members engageable with the connector to take up a portion thereof at an intermediate input member position.
