ABSTRACT:
Two embodiments of starting systems for internal combustion engines that prevent backfiring by precluding starting when the kill switch is energized. In one embodiment, the kill switch includes two pair of contacts, one for the kill circuit and one for the starting circuit, with the starting circuit contacts being normally closed and the kill circuit contacts being normally open. In the other embodiment, energization of the kill circuit also energizes a relay that opens the starting circuit.
