>>Now why would they outlaw two stroke engines??
There are very few 2 stroke motor cycles left on the road, as it's too
hard to make them meet emission requirements. Not outlawed, just easier to
make a 4 stroke meet the rules. There is also economy to consider. 2
stroke engines are lighter, and can usually produce more power for a given
capacity, but they are generally not as fuel efficient. If you watch the
motocross racing these days, the competitors have a choice here now of a
250cc 2 stroke, or a 400cc 4 stroke. Most of the top level competitors
will have both, and make a choice depending on the particular track they
are racing on.
Most of the new lawnmowers on sale now have 4 stroke engines. The
manufacturers and retailers are very quick to point out that these cause
less pollution. They also have warnings in the instruction manuals
regarding using them on sloping land, as the lubrication system can end up
not picking up any oil. This destroys the engine in short order, and is
not covered by warranty. Part of my yard has a steep slope, so I got a 2
stroke mower on purpose. Most small outboard motors are still 2 stroke
here, although there is a tendency for the larger ones to be 4 stroke.
