The FS-120S Ⅲ is fitted with the new O.S. PD-07 diaphragm type fuel pump and matching Type 70N carburettor incorporating a built-in pressure regulator. These features ensure that fuel/air mixture strength is maintained at a constant level through maneuvers, for consistent performance and reliable throttle response. In the interests of improved durability, certain ferrous parts that are particularly susceptible to corrosion in four-stroke engines, have a corrosion-resistant plating and, for the same reason, a special grease-packed twin-sealed rear ball-bearing is used. To maintain the four-stroke engine's reduced noise levels, the FS-120 Ⅲ is supplied with an O.S. E5040 silencer (muffler) of substantially enlarged volume, as standard equipment.
