It’s good that you care about that stuff. So do I. But what you have to remember is, once upon a time, the world was FULL of 2 stroke engines, just dumping great mounds of oil and raw gasoline into the water; and somehow, it survived. One little engine, running for a short time here and there, isn’t going to amount to a pee hole in the snow, in the Big Picture. I know it sounds kind of harsh but you have to admit, it’s true.
Long live American manufacturing!
