4-stroke cleaner? Nah!

The 12 year old Craftsman yard tractor is sitting in need of more repair. Recently, I did some major welding of cracks, reinforcing of the deck and frame, and built a new, super-heavy-duty front wheel beam. But yet another part crapped out.
So, as a small challenge, rather than jump right on repairing the tractor (yet again), I figured I'd try mowing the two acres (not flat, but with hills and ditches, not user friendly) with the 21-inch walk behind. The first time wore me out. Sunday was my fourth time, and I handled it quite well. Getting tough here, we are. But I suspect I'll get sick of this crap before long and get the tractor fixed.
One thing I noticed was that the 21-inch uses MORE gas than the tractor -- definitely some efficiency issues here. And, with no wind, and my back yard surrounded by trees and bushes, it leaves a haze in the air like fogging for mosquitos. It occurred to me that maybe in the lab, a 4-stroke tests out cleaner than a 2-stroke. But I'll bet in the real world of lawn mowers, after the new has worn off, a reasonably well designed 2-stroke will run much cleaner than the crapola 4-stroke (B&S) engines on most mowers.
Even though I change the oil on the B&S crap engine, it hasn't taken it long to start running dirty. And most people rarely change their lawn mower oil. A 2-stroke, by nature, requires a constant supply of new, clean oil. So, I'm thinking that, over the normal life of a walk-behind mower, a reasonably well desigined 2-stroke would be environmentally superior to and more durable than the alu-min-ium, splash-oiled 4-stroke waste of metal on most mowers.
I would like to invite the government EPA lab folks to come see the haze generated by my year old EPA-approved B.S. B&S and suggest they get out of the lab once in a while to view what happens in the real world.
