OS FS Alpha-155-P 4-takts metanol

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.
