Paul,
   Wondering if you or any other members might be privy to
   current manufacture of rotary chainsaws or weed trimmers?

   It's been done before and I seem to recall something from this list
   or my other internet wanderings of an engine manufacturer touting
   better emissions from rotary vs 2-cycle...

    KMS 4

The legendary KMS 4 from 1975 DOLMAR produced together with Fichtel &
Sachs the first chain saw with rotary engine.
