Claim:
1. An internal combustion engine comprising: an operator-controlled element; a supply channel for supplying combustion air for the engine; a throttle element mounted in said supply channel; said operator-controlled element being operatively connected to said throttle element to adjust the position thereof; a starter device having an operating position and a starting position; a fuel port having a free flow cross section and opening into said supply channel; a first ramp configured to control said free flow cross section of said fuel port in dependence upon the position of said throttle element when said starter device is in said operating position; said starter device being configured to enable a defined clear flow cross section in said supply channel in said starting position; said starter device including an actuation unit for setting said starter device in said starting position thereof; a latching unit for latching said starter device in said starting position; said operator-controlled element being operatively connected to said latching unit for unlatching said latching unit in response to a first actuation of said operator-controlled element after starting the internal combustion engine; a second ramp; said free flow cross section of said fuel port based on said second ramp being greater than a flow cross section adjusted for the same position of said throttle element based on said first ramp; said latching unit being configured to be unlatched in response to said first actuation of said operator-controlled element; said second ramp being configured to control said free flow cross section of said fuel port in response to said first actuation of said operator-controlled element after said unlatching of said latching unit at least up to a closing operation of said throttle element following said first actuation of said operator-controlled element; said first actuation of said operator-controlled element effecting an opening of said throttle element; and, said second ramp being configured to control said free flow cross section while opening said throttle element with said first actuation of said operator-controlled element.
