Candle Engine

This is a flame licker engine I started drawing up as I near the end of my current project. I'm always looking to the next thing and I lost interest in this as it is too "abstract" for me. I may design my own using this valve system. The pushrod and spring remain to be done. There are also some errors in the part appearances. I don't intend to finish but thought others may want to. I have included the original magazine article. The video is not mine, just one of this engine.
