Stephen J. King, of Florida, designed and built this 2-cylinder, 4-cycle engine in 2005. It has an open crankcase for visual effect while the engine is operating. It burns gasoline on spark ignition and utilizes a pressurized oil system to lubricate the crank, rod, and cam bearings. Open rockers on top require manual lubrication. It has a bore of 19 mm and a stroke of 15 mm and burns regular gasoline on electronic spark ignition. The tiny float bowls under the carburetors provide stability to the constant stream of fuel entering the carburetors. Other unique accessories include a starter and a small generator. The engine is 10″-long, 6″-wide, 7″-high, and 5 lbs.
