Abstract
The invention relates to a carburetor arrangement for an internal combustion engine (1), especially for a drive motor of a work apparatus such as a motor-driven chain saw, a brushcutter, a cutoff machine or the like. The carburetor arrangement includes a carburetor (2) having an intake channel (3) and an air filter (4) mounted upstream of the intake channel (3). The air filter (4) has an air filter housing (5). The intake channel (3) opens with an intake opening (6) in a housing base (7) of the air filter housing (5). The intake opening (6) can be covered at least partially by a choke element (8). The choke element (8) is held on a choke carrier (9) so as to permit a limited movement of the choke element.

- a carburetor defining an intake channel;
- an air filter housing including an air filter arranged upstream of said intake channel;
- said air filter housing having a base wall defining an intake opening communicating with said intake channel;
- and,
- a choke assembly including:
