The serial # 17 Circa Engine 1910 Ok , I was always wondered if I ever machined my own engine , I was thinking 'simple'. well come to find out this engine is far more complex than I imagined . And from what I have heard there was a man who was spying on the Wright brothers and mounted an engine on a bicycle before they had made the Circa . And of course it was way smaller than the Circa . Can anybody name the engine and the man who made it?
