A manually guided implement having an internal combustion engine, especially one embodied as a two-stroke engine, is provided, and also includes a crankcase and a carburetor. The implement has a fuel-conveying system for supplying fuel to the carburetor. Downstream of the carburetor, via a power line and a metering device disposed in the primer line, the fuel-conveying system is connected to an area that in the intake phase communicates with the crankcase. The metering device is controlled by the pressure in the crankcase.
