Abstract
A carburetor adjustment screw apparatus includes an adjusting screw (2) having a shaft (7) in screw threaded engagement with a carburetor body (4) and a head (8) by which the shaft may be rotated. A generally tubular open-ended housing (10) surrounds the head of the screw and a ring (11) is rotatably mounted in the open end of the housing. Stop means (19/20) limit the angular range of rotation of the ring. A plug (12) is mounted in the ring and engages the screw such that rotation of the plug effects corresponding rotation of the screw. The plug is movable relative to the ring between a first axial position wherein the plug can rotate independently of the ring and a second axial position wherein the plug engages the ring for co-rotation therewith such that the angular range of rotation of the plug is limited to the angular range of rotation of the ring.
