I wonder if the larger Efcos even come close to the EPA limits of 72gms/kwhr... I'm bettting they don't (unless they use a CAT muffler, no conventional 2 stroke can meet this level), and they are using the 3200 unit per year exemption available for the next two years to bring them in.
Other than a short model life, none of this matters to the end users.
I normally agree with what you say Lake (even if I don't admit it), but stop pigeon-holing two strokes. Just because people haven't started building cleaner conventional engines doesn't mean it can't happen.
At the 1900 Convention of Physicists the key speaker stated that everything major thing there was to know about physics had been discovered.
Guess he just didn't know about Special Relativity or Quantum theory.
