Working machine having a single operation unit

摘要: The present invention provides a working machine having an internal combustion engine. includes single operation unit comprised of rotatable body adapted to be selectively rotated between engine-stop position, engine-start position and choke-activation valve about rotation shaft, arm attached the shaft link member moved in its longitudinal direction transmit movement arm. has distal end coupled with proximal body, extends ends. is formed elongated slot receiving therein. When from allowed displace relative along without causing any direction. restricted displacement so that
