Abstract
A carburetion arrangement for an internal combustion engine of a manually guided implement is provided. The arrangement includes a carburetor having an air channel, the cross-section of which is variable via a butterfly valve. An auxiliary carburetor having an auxiliary air channel is, in a flow conducting manner, connected in parallel to the air channel, whereby the auxiliary air channel opens into the air channel downstream of the butterfly valve. Disposed in the auxiliary air channel is a starting valve that includes a flow control device, wherein the starting valve alters the flow resistance of the flow control device as a function of the differential pressure that is present.
