A carburettor (13) is arranged in a chamber (14), and an air mouthpiece (15) conducts combustion air to the carburettor chamber. The air mouthpiece has a first air inlet located near the fan wheel periphery, via which the centrifugally cleaned combustion air is conducted to the carburettor chamber. The air mouthpiece has a second air inlet located near the cylinder (10), permitting feed of preheated combustion air to the carburettor chamber. |
