    摘要: A cap (40) and method for limiting the range of adjustment of a fuel flow metering valve (36) in a carburetor. The cap (40) has a body (82) with an arm (84) projecting generally radially outwardly therefrom to abut against a stop carried by the carburetor to limit valve rotation and a passage (86) therein for telescopically axially receiving the head end (62) of a shank (60) of the valve (36). Portions within the passage (86) enable the cap (40) to be retained in the shank (60) of the valve (36) in a freely rotating first position during assembly and arm orientation, and in a second position securing the cap (40) to the valve (36) to limit adjustment and maintain emissions calibration. Preferably, the cap (40) may also be moved to a third position to releasably drivingly engage the valve (36) to perform fuel flow adjustment before securing the cap (40) to the valve (36). The cap (40) can also be prepositioned angularly relative to an adjusted position of the valve (36) before it is moved to its second position on the valve (36) to limit the extent of subsequent adjustment of the valve (36).
