This is 86cc size Twin Cylinder 2-stroke Gas Engine from Fuji Imvac.
FEATURES: Gasoline engine for large scale aircraft applications
CDI (Capacitive Discharge Ignition) One-piece, solid state Electronic
Ignition with no breaker points. Makes it very dependable and
virtually maintenance-free.
Machined using highly-specialized state-of-the-art CNC equipment,
which makes for better overall quality and a tighter parts fit.
Two decompression valves allow turning the engine thru easily during
starting. Either valve can be pushed IN, and once the engine fires,
the valve automatically snaps OUT for running compression.
Valves are located in the center part of each cylinder. The front
valve is easily accessible by hand in airplanes with open cowlings.
The rear valve can be operated by a firewall-mounted servo in
airplanes with closed cowlings. (For firewall-mounted servo, the
modeler must decide where and how to install it, and may need an
extra channel on the radio for operation.)
One-set so you can fly all day without having to change
needle settings on the easy-to-understand Walbro .
Propeller is held securely by a knurled hub, and two other optional
lengths of hubs are available for different cowling sizes.
Muffler is designed specifically for use in R/C airplanes having
three exhaust ports instead of one. The mufflers mount to the
engine's cylinder heads on both sides.
Heads are painted Light Blue and crankcase is natural Silver
Cylinders utilize chrome plated internal construction for long life
