Abstract
A carburetor throttle control device is provided having a positive feel and ability to precisely position a throttle valve. The lever includes an annular rim that has a plurality of notches corresponding to the angular positions of the throttle plate. A detent is piloted over the throttle shaft and is fixed or captured relative to the carburetor body between the carburetor body and the throttle lever, received in the annular recess of the hub. The detent includes a flexible or spring-type arcuate arm attached to and extending about a portion of the hub and having a protrusion extending therefrom. As the lever is rotated, the protrusion mates with the throttle position notches in the hub of the lever. The protrusion thus positively indexes the lever between positions. A throttle adjustment mechanism is also provided for manually adjusting the position of the detent, and thus the idle speed of the engine.
