ABSTRACT:
A carburetor arrangement for a two-stroke engine (1) is for a portable handheld work apparatus such as a motor-driven chain saw, cutoff machine or the like and has an intake channel (22). The intake channel (22) is partitioned by a partition wall (11) into an air channel (8) and a mixture channel (21). A fuel opening (27, 28) for supplying fuel to the two-stroke engine (1) opens into the mixture channel (21). The carburetor arrangement has a carburetor (17) having a carburetor housing (18) wherein an intake channel section (32) is formed. A throttle flap (24) is pivotally journalled in the carburetor housing (18). A good partitioning of the air channel (8) from the mixture channel (21) results with a simple manufacture of the carburetor (17) when a partition wall section (31, 48, 58, 68, 78, 88, 98) is configured as a separate component upstream of the throttle flap (24) and is held in the intake channel (22).
