ABSTRACT:
A vacuum responsive carburetor linkage includes a housing at least partially defining a vacuum chamber therein and an end wall further defining the vacuum chamber and movable relative to the housing between extended and retracted positions whereby the chamber is extended and retracted. The housing is connected to either the accelerator pedal linkage or carburetor throttle lever and the end wall is connected to the other of the accelerator pedal linkage or carburetor throttle lever. A vacuum conduit establishes communication between the vacuum chamber and a vacuum source in the carburetor of the internal combustion engine. Thus when the carburetor vacuum is low, lost motion is permitted between the accelerator pedal linkage and carburetor throttle lever whereas when the carburetor vacuum is high, the carburetor throttle lever is moved in substantially direct response with the accelerator pedal linkage.
