Abstract
An adjustment safeguard for a set screw on a carburetor includes a cap held non-rotatably on the head of the set screw. The cap is surrounded by a coaxially positioned wall sleeve fixed to the housing. A rotation stop is fixed to the housing to limit the angle of rotation of the cap in the sleeve in the rotational direction of the set screw. A through-opening in the cap permits inserting a tool into an engagement opening in the head of the set screw to avoid destruction by introducing too much torque into the adjustment safeguard. The form and opening width of the through-opening is limited by the use of a metal material such that a tool larger than the adjustment tool is not able to be inserted through the through-opening into the head of the set screw. The engagement opening is flexible to limit a maximum allowable adjustment torque.
