Abstract
The invention relates to a method and a control device for operating an internal combustion engine of a portable work device, said method having the following method steps: a) storing a starting ignition curve for specifying an ignition time after a startup time of the internal combustion engine and an operating ignition curve for specifying the ignition time in a speed range assigned to the nominal operation of the internal combustion engine, b) reading the current engine speed, c) reading at least one time value which indicates the time that has elapsed since a reference time, wherein the reference time can relate to the startup time of the internal combustion engine, and d) determining and/or initiating a switchover process from the starting ignition curve to the operating ignition curve on the basis of the current engine speed and the time value.
