Okay, moving on with our petrol engine discussion, I am going to deal with the upper section of the engine and the use of common terms. The reason for this is to give some readers an insight into the correct names and terminology when dealing with their engine. I have heard it in model shops, and I have received it in conversations at flying fields when a modeller is asking something about his engine or a part that is a problem. Along the lines of, "Hey Ivan, you know that Fizgig 69 engine I have?" (Maybe I do - probably I don't or I haven't seen his engine!) "Well, the thingy that goes into little chamber on the side of the bit where the screw goes in has bent. How do I get the screw out and where can I buy another thingy?" Blimey, mate, I haven't a blasted clue, as I have no idea what you are talking about.
