A manual starter for an engine includes a main housing, an output shaft, a
spring housing, a spring, and an attachment unit. The output shaft is
disposed at least partially inside the main housing, and is configured to
supply a starting torque to the engine. The spring housing is disposed in
the main housing. This spring is disposed in the spring housing, and is
configured to receive an initial force from a starter cord and to supply
the starting torque to the output shaft. The attachment unit is
configured to selectively couple the spring to the output shaft before
the engine has started and decouple the spring from the output shaft
after the engine has started.
