  • Four-Stroke Rear Intake Gasoline Engine with Muffler and Onboard Electric Starter
  • Plasma Chrome Plated Steel Cylinder pressed into a cylinder cooling jacket unlike the OS GF40 40cc which is one piece aluminum but the valve seats are part of the head.
  • The Gaui F-50 has Bronze one-piece valve seat inserts and valve guides.
  • Monster sized Aluminum Connecting Rods Bronze Bushed at both ends unlike the OS GF40 which uses needle bearings and bronze bushing on the smaller ends.   All design decisions centered around durability and reliability.
  • Gaui recommends a high-octane (Premium) gasoline. Av-gas is not recommended.  Mix the gasoline with high quality 2 stroke oil at a ratio of 20:1.  One gallon of gasoline mixed with 6.4oz of 2 stoke oil provides the recommended 20:1 mixture.
  • Carburetor adjustment high end needle is opened 1.5 turns, plus or minus .5 turns.  Low end is the same as above.
  • Propeller recommendations are 20x10 or 21x10.  The propeller attaches with six 4mm bolts.
