Re: 4-stroke or 2-stroke?
Just look at the engine cover. They usually say "Four-Stroke" if they are indeed a four stroke. If it is a two stroke there would be no such text on the cover. If the engine has a resevoir under the engine cowl it is a two-stroke. If the engine has a dip stick to check the oil in the crankcase, and the engine has an oil filter that looks like the one on your car (just smaller) it is a four-stroke. Although a two stroke also has a dip stick, it measures the oil in the oil resevoir, not the crankcase. Just looking at the engine should also be a clue. Do you see camshaft covers? Yes = four stroke. No = two stroke.
