Unknown Twin Cylinder Ignition 1. 7cc Model Airplane Engine. 10 Vintage Fuel Tank
Item History & Price
This is a vintage twin cylinder ignition model airplane engine that is about 0.1 cubic inch total displacement (0.05in x 2). I believe this engine to be scratch built, and by a skilled builder. The engine employs a clever variant of the Scotch Yoke (with integral rear ignition timer) to provide for simultaneous (boxer) twin firing. The design reminds of the G-Mark (although this engine would have been earlier than G-Mark). The engine turns over smoothly with good 0.05...in compression on each cylinder. The pistons are lapped and baffled. The fuel tank is built-in to the needle valve assembly (which has integral intakes). The spark plugs are OK branded. All in all this engine has a number of rather clever design features. I have never seen another one like it. This is a nice one for your interesting small ignition twin model engine collection.
