ABSTRACT:
An improvement to apparatus for adjusting the position to which a carburetor throttle valve closes. A switch 1 senses when the throttle valve moves toward its substantially closed position. The switch includes a set of electrical contacts (3A and 3B). A pin (11) engages an extendible and retractable member (M) for moving one the contacts into contact with the other when the throttle lever contacts the member as the throttle valve closes. A spring (5) biases the pin against the member to preload the member. An adjustment screw (21) adjusts the position of the electrical contacts relative to each other.
