Some other visual clues: Conventional two-stroke doesn't have any timing gear or push rods, rocker arms, conventional valves. Carb is not attached up near the head, but down low on the crankcase, as fuel is pulled into crankcase by the piston going up. There have been wonderful two-strokes that did not take fuel in through the crankcase, like the beautiful engine that GM made for years: A Rootes-type supercharger blew air into the cylinder through holes around the periphery, near the bottom of the cylinder. Conventional exhaust valves at the top of the cylinder allowed gases to go out as the piston came up. At some point, the holes were covered, the valves closed and fuel was injected in. This engine had a wonderful sound, because a six sounded like a twelve. You used to hear them in pretty big trucks, and they were used in GM buses since maybe 1940 or possibly just a bit earlier. The city versions of these buses had a two-speed automatic, with a torque-converter of a different design from those in modern cars. At a certain road speed, the driver let up on the gas and direct-drive came in with a noticeable "clunk!" I guess these engines must have been polluters, because they disappeared at some point. Time to go to the internet, I guess. I have some old auto repair books that explain this engine, and if anybody reading this just can't live without seeing the explanations and diagrams, send me an e-mail and I'll see if I can scan the book and send you the pages needed.

He'll be busy working and I�m handing him tools and he says, "give me that..." and I�ve already got it in his hand or "hand me that....."and I�ve got the portable light right where he needed it placed to see.
