Benz Patent Motorwagen - Throttle

To start, let fuel into the system by hand, turn on the lubrication system then spin the flywheel by hand. There's no fuel pump. The driver must occasionally stop and feed in more fuel. Speed is controlled with a lever. Pushing it forward tightens a belt around a spinning metal barrel, increasing power to the wheels.
