Abstract
To provide for ignition advance as the speed of the engine increases, a frequency-dependent circuit formed by a series RC circuit is connected in parallel with the control path of a switch in series with the primary of the magneto ignition coil so that the switch will be controlled to cut off or to open earlier as the speed increases.
