摘要

A method for operating a carburator arrangement for an internal combustion engine, in particular for a by a pulling cable, since the internal combustion engine to be started in a manually operated tool, wherein the carburator arrangement a suction channel section (9) and one in the intake duct section (9) running of the fuel passage (8) has, wherein said fuel passage (8) with a fuel-filled reservoir chamber (4) is connected, and depending on the negative pressure in the intake section (9) supplies fuel, and with a starting device (30) in order to increase the negative pressure in the intake section (9) during the starting process, wherein between the mouth (ha) of the fuel passage (8) into the intake conduit section (9) and the accumulator space (4) a switching valve (40) is arranged, wherein the switching valve (40) with a control unit (41) is connected, and wherein the control unit (41) of the on / off valve (40) as a function of at least one operating parameter of the internal combustion engine (28) is actuated, wherein the operating parameters of the rotational speed of the internal combustion engine is, characterized in that, after exceeding a limit speed (g) of the on / off valve (40) is closed and after reaching of a following speed maximum (d_{a maximum}) the switching valve..
