This is my version of the Jan Ridders 1 Cylinder - Glass 4-stroke Gasengine with rotary valve. The engine runs with the Vapour "carburator". By having only low power the engine still runs very good. While running you can see the combustion fire inside the Cylinder. Very cool! Original Plans on Jan Ridders Homepage.
