Fuel system purge and starter system

摘要

A recoil starter (11) for an internal combustion engine has a housing with a pulley (66) carried at least in part for rotation therein. The pulley (66) is arranged in operable communication with a crankshaft of the engine. A pull cord (18) is wound about the pulley (66) with one end of the cord being arranged to be pulled by a user to rotate the pulley. An actuator (106) is carried for rotation in response to rotation of the pulley. A pump (16) is arranged for actuation in response to rotation of the actuator (106) to provide fresh liquid fuel to a carburetor and remove fuel vapor and stale fuel from the carburetor and deliver it to a fuel tank (14) prior to starting the engine.
