A few years ago, Philip Duclos designed a rather homely (or so I thought) little engine with an oscillating cylinder, not unlike one of Elmer Verburg's steam powered "wobblers". The REALLY BIG difference was that this engine was gasoline powered.----and---It was a hit and miss engine---and it was air cooled. It was a very clever design, and according to Philip Duclos, it ran well. I want to build something different enough to be interesting, and to add my own personal touches to "pretty it up" a bit. I give Philip full credit here for his original design, and hope that wherever he may be now, that he smiles a bit when he sees what I am doing to his "Whatzit" engine.----Brian
