An intake passage (15) connects the carburetor to the crankcase and the carburetor chamber is connected via an inlet passage (21) to the fan housing at the outlet side of the impeller for centrifugal purification of combustion air. The carburetor chamber (17) has an opening (22) connected to atmosphere or to a lowpressure zone of the fan housing (19). |
