Abstract
The invention is directed to an arrangement for controlling the intake air for the carburetor of a hand-held portable tool such as a motor-driven chain saw or the like. During winter operation, the cooling air that is heated by the engine cylinder is carried through a pass-through opening to the carburetor. During summer operation the pass-through opening is blocked by a slide that is pivotally mounted on a pivot axis. The slide selectively opens or closes the pass-through opening and is configured as a deflector which, in its open position baffles the heated cooling air from the engine cylinder and guides it toward the carburetor.
