>The "Pollutants" being mostly CO, I'm guessing.
Partly burned hydrocarbons, that contribute to air pollution.
There are no catalytic converters on lawn mowers and some lawn
equipment burns oil mixed in with the gasoline.
> IMO, who cares?
I do. The air quality (what stuff I breathe) could be much better.
Downtown looks like there is a brown ooze surrounding it at times.
It actually can kill those who are vulnerable. Other places such
as Chinese cities are much, much worse, of course.
>The main real concern is how much gas was burned.
I disagree. *How well* is the main concern when it comes to
pollutants. A big thermal generating plant has all kinds of controls
and things like scrubbers so that most of what comes out of the stacks
is just steam. None of that can be afforded on a $200 lawn mower.
Only *some* of it can be put on every automobile.
You can even burn nasty stuff like dioxin-laden PCBs (not the
electronic variety) safely and completely with the proper controls
and equipment. A small uncontrolled PCB fire can render an entire
office building unoccupiable just from the soot (happened in

>And why would they assume "it's poorly tuned" anyway?
Maybe because few people tune their lawn mowers. A poorly tuned car
produces something like 100 times the pollution of a properly running
car, so the gas consumption means little. That is what is driving the
inspection and certification anti-smog programs in California, Ontario
and elsewhere. But lawn mowers are not subject to such inspection.
Cars are so good now that it's reportedly hard to reliably off
yourself from the CO, you (well, not *you*) might just be left
