Art,
Another issue with avgas is that it contains lead which pollutes the water  
the exhaust goes into. Not environmentally friendly and frowned (prohibited 
from  using) upon by most states.
Most marina's and a few gas stations close to Lake Hartwell sell boat gas  
which is ethanol free. I also use it in the tractor, tiller, chain saw, 
SeaDoo,  wife's Chaparral and leaf blower. It costs more (about $.50 a gallon) 
but I  don't have the carb and fuel line issues to deal with.

Marlin,

What have you learned about the octane effect on the  engine.  Avgas is 
typically 100 octane, occasionally available at  80/87.  I haven't seen this 
solution used, but it sounds plausible if it  does not damage the engine.  As 
an oddity, the Exxon station at Lavonia,  Ga (lake Hartwell) has non-ethanol 
now.  I doubt you could find non in  the Annapolis/DC area, and only a few 
south along the  Potomac.
