A circuit to be utilized in combination with an ignition system which is responsive to a start signal supplied thereto for maintaining the ignition system in a start mode of operation while starting of the internal combustion engine is controlled by the ignition system. The circuit is responsive to termination of the start signal to provide transitioning of the ignition system to a run mode of operation only during the current ramping period when the ignition coil of the ignition system is being charged prior to the end of a firing cycle when the coil is discharged to provide spark to operate the engine. Start retard and transitioning of the system from start to run modes is provided utilizing a single capacitor.
