Some old cars had a control which opened up vents in the cylinder heads
to allow an underpowered starter motor to spin the engine. When the motor
had got the engine spinning fairly fast, you would knock the vents closed
and let the inertia stored in the flywheel overcome the compression and
start the engine.
