Abstract

In order to improve a limiter cap (300; 300′) for limiting the adjustability of at least two set screws or valves (200), which are arranged side by side, with each set screw or valve (200) including at least one retaining nose or stop leg (240), extending in the transition area between the screw head (210) and the screw needle or valve needle (220) in a ring shape around the external circumference of the screw needle or valve needle (220), in particular for limiting the adjustment of the fuel flow through a carburetor (400; 400′), in such a way that inadvertently pushing the limiter cap onto the screw needle thus prematurely blocking said screw needle, already at the time when the (basic) carburetor adjustment takes place, is safely prevented, it is proposed that the limiting cap (300; 300′) is attached to each of the set screws (200) in particular in a way so as to be self-attaching, and/or in particular such that the limiter caps (300; 300′) engage each other with locking action, and/or without any further auxiliary means or without any further supplementary part.
