An arrangement for providing ignition pulses for an internal combustion engine while at the same time inhibiting ignition pulses from being applied when said engine is operated in the improper direction. Ignition pulses are produced through an ignition coil which has its primary winding connected to a capacitor charged through a magneto generator. Discharging of the capacitor is controlled through a thyristor which, in turn, is fired through the application of pulses derived from pulse emitters. The thyristor is switched to the conducting state, during improper operating direction of the engine, by the voltage pulse which causes charging of the capacitor when the thyristor is in the nonconducting state.
