This model shows the internal structure and operating principles of an air cooled two-stroke engine.

• Solidly constructed out of aluminum and plastic
• This large model measures 10.5 x 6.5 x 5" and is mounted on an 8 x 8 x 2.5" base
• A placard on the base labels all key components

Hand powered motion supplied through a crank demonstrates the moving parts of the engine. The crank shaft and piston cycle through the stages of the two-stroke process as the hand crank is rotated. A simulated spark plug uses a small lamp to indicate the firing point.
