Please note that this engine is not supplied
with any tools (e.g. Allen keys, wrenches, etc.)
This is a FS (Alpha) series of the single
cylinder overhead valve four cycle engine
equipped with a fuel pump system. It offers
broad power band to suite a variety models
types. The PD-08 pump designed for bigger
models and the 61R carburetor integrated with
regulator ensures stable fuel delivery
irrespective of model attitude and fuel level
change. It is suitable not only for 70 size scale
and sport models but also for aerobatic models
which require stable power and linear throttle
response. O.S. pump system is easy to handle
because it supplies fuel direct to the carburetor
without pressurizing the fuel tank. (Be sure to
vent the fuel tank). New lubricating system
eliminates the need for breather tubing from
the crankcase. The F-5030 silencer and Type
F plug are supplied as standard.

turned 180 degrees to reverse needle
position.
