Abstract
A carburetor (18) has a carburetor housing (17) wherein an intake channel (19) is guided having a flow cross section of less than 3 cm2. The carburetor (18) includes a partition wall (11) which partitions the intake channel (19) into a mixture channel (21) and an air channel (8). The partition wall (11) runs in the longitudinal direction of the intake channel (19). The carburetor (18) has a throttle flap (24, 64) pivotally journalled on a throttle shaft (25, 45, 55, 65, 75). A venturi (23) is formed upstream of the throttle shaft (25, 45, 55, 65, 75) in the mixture channel (21). A fuel opening (28) opens into the mixture channel (21) at the venturi (23). A device for dethrottling the mixture channel (21) and/or for dethrottling the air channel (8) is provided in order to compensate or equalize the nonuniform throttling of the air channel (8) and the mixture channel (21) by the throttle flap (24, 64).
