Abstract
An air-cooled engine for a working machine includes a fan cover, a muffler protector, and an insulator. The fan cover has a guide opening for guiding a cooling air toward an exhaust muffler. The muffler protector has air discharge holes for discharging the cooling air, which has been introduced through the guide opening into a guide passage, in a direction away from the working machine. The insulator has a deflector section bent toward a carburetor so that the cooling air having passed through another guide passage between the insulator and cylinder barrel is guided by the deflector section in a direction away from the working machine.
