Hello; I guess that I didn't make it clear enough what I meant by "the rest of the world", what I meant was that at one time you could buy two stroke motorcycles, lawnmowers, even cars. Now even weed whackers are four stroke, gen sets, outboard motors, even trials bikes are four stroke. My Honda lawn mower has an overhead cam.
I do concede that two strokes as less expensive, but except for power saws, they are becoming rare.
EPA air pollution regulations more than anything else is what has killed two stroke motorcycles etc. Even off highway engines are coming under the gun.
