Patent abstract

A carburetor arrangement for a manually-guided implement operated by an internal combustion engine. A carburetor supplies a fuel/air mixture to the engine, with a butterfly valve being disposed in the intake duct of the carburetor and with a choke valve being disposed upstream of the butterfly valve. A start lever is provided for actuating the carburetor in a start phase, and acts upon the choke valve. The start lever can be shifted in a direction of actuation and in an unlocking direction that is independent of the direction of actuation. The start lever can be locked in a rest position relative to the direction of actuation, and after being shifted out of the rest position in the unlocking direction is shiftable in the direction of actuation.
