I don't see the need for a timer, unless you want it be fully automated with the ignition switch. You could just use a momentary on-off switch, which you press for a few seconds to fill the carburettor before depressing the accelerator pedal and engaging the starter motor, (ideally a reduction gear starter motor).


It may only be required when starting from cold when the car hadn't been used for a long time.
