Abstract
A starter mechanism for an internal combustion engine having a spring that is wound during the starting operation of the internal combustion engine. As the operator pulls the starter rope of the engine the starter spring begins to wind creating a force within the spring. Once the spring force overcomes the compression force of the piston the spring will unwind thereby turning the crankshaft of the engine and consequently starting the engine. The starter rope is returned to the housing of the starter mechanism by the use of a rope return spring.
