Abstract: A chainsaw as a working machine, which switches among stop, drive, and choke operations of an internal combustion engine, includes an operation lever that is turnable, a turning member turnably combined with the operation lever, and a torsion coil spring holding abutting of the operation lever and the turning member. The turning member is coupled to a choke operating member via a choke rod and is regulated in turning from drive position to stop position. When the operation lever is turned from drive position to choke position, the turning member also turns to move the choke rod, by which the choke operating member closes the choke valve. Meanwhile, the operation lever is turned from drive position to stop position, against the turning force of the torsion coil spring.
