Abstract
The invention relates to methods and means of regulating the speed of a two-stroke combustion engine. An arrangement for alternating an ignition timing relative to a top dead center position is provided. For a given engine speed, the ignition timing may be step-wise adjustable. One or more steps may be used while alternating between two ignition timings. The ignition timing may be adjusted when the engine speed increases above a threshold engine speed.
