The engine is the source of power, bringing power to modern society. While the engine must be started by a starter. The common starter is an electric starter that needs a battery to provide energy. Other starting methods like air starter, require an external system to provide energy. All of them rely on external power. Once it lacks external power, the engine is “dead”.

The mechanical starter is the ideal solution during the above situations. Cqstart spring starter, using a simple mechanical mechanism, stores the energy by compressing the springs and releases the spring’s potential energy by pulling the trip lever to turn the engine’s flywheel.
