This is an all brass, 2 cylinder, 2 cycle, opposed, air cooled, gas engine. It has a ¾” bore and ¾” stroke. It measures about 6” x 6”. The engine incorporates a crank with a double throw, but the connecting rods are offset so as to keep the cylinders in a straight line. With the double throw crank, both cylinders fire at the same time. There are steel liners in the brass cylinders. This engine uses glo-plugs, thus eliminating ignition by battery, coil, and spark plugs. The construction book is 8 ½” x 11” has 26 pages, and is spiral bound. All drawings are full size.
