Abstract
For an internal combustion engine carburetor (10) having a throttle valve (14) and a choke (22), the throttle valve (14) and the choke (22) can be brought in dependence on each other to different sets of predetermined operating positions which are appropriate respectively for the operating of the engine at no-load, for a cold start, and for a warm start, with a safe and definite adjustment being achieved in that the switch (19) is placed directly on the carburetor (10) and is connected with the choke (22) and in that the choke (22) and the throttle valve (14) are coupled with each other over mechanical couplings (16, . . . 21) with the switch (19) having a different position for each set of throttle valve and choke operating positions.
