This Novoexport 2.5KP 2-cycle, 1-cylinder engine was also donated by Mr. Mack, who purchased it new during “The Cold War Era.” Like the CO2 engine, it is still new in the molded styrofoam box and complete with instructions (in Russian) and spare parts. A very long aluminum tuned exhaust pipe is also included. It was distributed by Novoexport in Moscow, USSR. We presume by the name that it displaces 2.5 cc. Also included is a handsome pointed aluminum spinner for a 2-bladed propeller. A translation of the instructions is underway.
