Abstract
An internal combustion engine has a supply channel for supplying combustion air. A throttle element is arranged in the supply channel. The engine has a starter device which enables a defined free flow cross section in the supply channel in a starting position. The starter device latches in the starting position and the latching is released by actuating an operator-controlled element. A first ramp controls the free flow cross section of the fuel port depending on the position of the throttle element. The free flow cross section of the fuel opening is controlled by a second ramp. The free flow cross section of the fuel opening, which is set using the second ramp, is greater than a flow cross section set using the first ramp for the same position of the throttle element. A favorable performance of the engine after starting thereof is achieved.
