This is 86cc size Twin Cylinder 2-stroke Gas Engine from Fuji Imvac Inc.
FEATURES: Gasoline engine for large scale aircraft applications.
CDI (Capacitive Discharge Ignition) One-piece, solid state electronic
ignition with no breaker points, making 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 the engine to be rotated easily during
starting. Either valve can be pushed in, and once the engine fires,
the valve automatically recloses 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 needle valve so you can fly all day without having to change
valve settings on the easy-to-understand Walbro carburetor.
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
engines' cylinder heads on both sides.
Heads are painted light blue and crankcase is natural silver.
Cylinders utilize chrome plated internal construction for long life
Included metal motor mounts.
Tools and one extra of each mounting bolt included.
Optional electric starter with mounting hardware is available.
Optional spring starter with mounting hardware is available.
