200-size power in a 120-size package!

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!

Also included: F-6020 muffler, Type F glow plug & PD-08 pump.
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.
2-year limited warranty.
