摘要： A motor driven implement having an internal combustion engine having at least one cylinder and at least one carburettor, which is disposed in a carburettor chamber, which is separated by an intermediate wall from an engine compartment, wherein a fan wheel is further provided by which means air from the engine compartment can be introduced through an engine compartment opening in the intermediate wall into the carburettor chamber. A warm air opening is provided in the intermediate wall, through which the air heated over the cylinder can be introduced into the carburettor chamber and wherein an adjusting element is provided which can be brought into a summer position in which the engine compartment opening is open and the warm air opening is closed and which can be brought into a winter position in which the engine compartment opening is closed and the warm air opening is open.
