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 70R carburetor integrated with
regulator ensures stable fuel delivery
irrespective of model attitude and fuel level
change. It is suitable not only for 120 size scale
and sport models but also for aerobatic models
which require stable power and linear throttle
response. The 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-6020 silencer and
Type F plug are supplied as standard.
Note: Since the 70R carburetor is integrated
with the regulator, it cannot be turned 180
degrees to reverse needle position.
