| This tiny internal combustion engine has a single cylinder. |
| The engine has a large brass flywheel and a small aluminum pulley for running accessories. |
| Bottom of the the screen: crankshaft. Top: piston. |
| Ignition is provided by a tiny working spark plug. |
| This basic carburetor controls the fuel air mixture. |
| The engine can run on butane, propane or a mixture. |
| The charge for the spark plug comes from this piezo igniter. |
| Open the gas valve, spin the flywheel and the engine roars to life-- occasionally spitting blue flames from the dual exhaust pipes. |
