This is the kit that enables young mechanics and auto enthusiasts to build and display a working 1/10 scale model of a 4-cylinder internal combustion engine.

The kit has over 100 ABS plastic parts that fit seamlessly together using the included tools. A Haynes Manual--the definitive auto repair reference since 1965--guides construction with complete, step-by-step instructions and vivid, clearly printed diagrams. A transparent cylinder block enables young mechanics to see how the connected parts work in concert to power a vehicle. Lubricated with small applications of vegetable oil, the engine operates using a small battery-powered electric motor (requires two AA batteries) which makes an ignition sound while firing the spark plugs; the valve sequence cycles, the pistons move, the shaft rotates, and the timing belt moves with the radiator fan belt.

Ages 12 and up.

8 1/4" H x 10 1/2" W x 5" H. (2 1/4 lbs.)
