ABSTRACT:
A solid state ignition system is provided for a two cycle internal combustion engine. A low speed limiter unit includes an electronic spark advance controller means connected to the ignition system to automatically advance the ignition angle by a substantial amount below a desired low limit speed. A speed sensing means is connected to sense the engine speed and at the selected minimum engine speed actuates the advance controller. The advance controller preferably has an asymmetrical rate of response, producing a relatively rapid advance output and a relatively slow retard output in response to changes in the speed sensing means.
