Carburetor altitude compensator apparatus (20) includes fingertip adjustable fuel to air mixture adjustment screw (22). The adjustment screw (22) includes a tracking member(30) rotatable therewith and cooperating with a graduated scale (42) to indicate the altitude at which optimum fuel/air mixture is derived for any given setting of the adjustment screw (22). An indentation (34) cooperates with the tracking member (30) to limit the range of possible adjustment of the adjustment screw (22) so as to avoid engine damage regardless of what adjustment the adjustment screw (22) is set at. |
