...To answer your question, if you want to get a rebuilt carb try Maibach equipment or Korves. There are others, but don't come to mind at the moment.
    If you can find the little brass tag that John was speaking of, it's a brass disc riveted to the carb, get a rebuild kit for it from the local AGCO dealer. You can rebuild it right at the kitchen table!....with permission of course. <!-- s:wink: --><img src="{SMILIES_PATH}/icon_wink.gif" alt=":wink:" title="Wink" /><!-- s:wink: -->  
             lots of luck.    Cal
