A mechanical fuel pump includes first and second flexible members disposed within a pump body. The first flexible member is deflected in timed sequence with a rotating engine member. Deflection of the second flexible member is limited to select the amount of fuel expelled from the pump for each engine cycle. A stop member is movable in response to movement of an engine governor and throttle to result in increased fuel and air being supplied when the engine encounters a load.

1. A variable pump for use in an internal combustion engine, the pump comprising:a pump body; first and second displaceable members interconnected with said pump body, and movable in response to an actuating force; and an adjustable stop member movable with respect to said second displaceable member

1. A variable pump for use in an internal combustion engine, the pump comprising:a pump body; first and second displaceable members interconnected with said pump body, and movable in response to an actuating force; and an adjustable stop member movable with respect to said second displaceable member; whereby displacement of said second displaceable member in a negative direction is limited as a function of the position of said adjustable stop member; wherein said first and second displaceable members include first and second flexible members, respectively, and said first flexible member is displaceable in response to said actuating force; and wherein said first and second flexible members at least partially define a pump chamber within said pump body, and wherein pressure in said pump chamber is increased in response to the deflection of said first flexible member and the limitation of deflection of said second flexible member.
