Description:

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
CNC Machined
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 cowls
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
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.

One of many motors I have purchased for planned projects which I will not be using. This motor was purchased as "new" from a member on RCU several years back but on very close inspection may have been started once - not sure but for practical purposes the motor is basically new. The specifications were pulled from the internet and represent the best information that I can find on the BT-86.
The motor has been stored in an air conditioned / heated environment.
Included in the price is a NIP spring starter for the BT-86.
