Abstract

A carburetor (1) for an internal combustion engine has an intake channel section (3) wherein a throttle element and a choke element are supported to pivot about respective rotational axes (34, 35). The carburetor (1) has a starter unit which has an operating position, an off position and at least one start position. In the start position, the starter unit fixes defined positions of the throttle element and the choke element. A simple manipulability and a multifaceted operational use of the carburetor (1) are achieved when the starter unit includes an actuating lever (29, 69) and an intermediate lever (18, 68) having respective rotational axes (28, 37) which are at a distance (c) to each other at least at the elevation of the intermediate lever (18, 68) and when the actuating lever (29, 69) acts on the throttle element via the intermediate lever (18, 68).
