Description

how do you get 200-size power from a 120-size engine? O. S. Calls it the fs155-a. Since the fs155-a is a pumped 4-stroke, you ’ll enjoy 2. 6 hp at all times, regardless of tank position, attitude or fuel level. Its novel recirculation system bathes working parts in constant lubrication, for less friction and wear!

  • the same 2. 6 horsepower as many 200-size power plants — with the dimensions and weight of a 120-size engine
  • because it ’s a pumped 4-stroke, you ’ll enjoy plentiful power regardless of tank position, attitude or fuel level
  • instead of oil venting through the crankcase, it ’s re-circulated to lubricate working parts — reducing friction and wear as well as cowl cleanup
  • includes the 70r regulating carb for superior throttle response and precise fuel metering
  • also included: f-6020 muffler, type f glow plug and; pd-08 pump
