[Rhodes22-list] Carb problems with NISSAN outboards?

[Lou Rosenberg]

  Peter, Bill
  Sorry to go back to this post but I have found some word of mouth 
info on the Nissan/ Tohatsu motors and want to confirm it with anyone 
on this list's experience.
  I heard from a sailor in my marina that the 2004 Nissan outboards DO 
NOT  RUN WELL AT ALL with  ETHANOL  added to the fuel.  In NYC we 
have ethanol added during the some parts of the season .
  Does any one have any experiences with bad carbureators on the 
NISSAN or Tohasu OB motors?
