Abstract
A carburetor assembly (1) has an intake channel section (30) and an air channel section (31). In the intake channel section (30), a throttle element and a choke element are arranged. An air control element is arranged in the air channel section (31). A first coupling unit (25) is provided which defines the position of the throttle element in at least one start position of the carburetor assembly (1). A second coupling unit (26) couples the position of the air control element in at least one operating state to the position of the throttle element. To ensure a reliable start, the choke element is held in at least one start position by the first coupling unit (25) and the second coupling unit (26).
