There are two camps in the carburetor rebuilding industry: those who believe that oxygenates cause problems, and those who don't. I have said much elsewhere on this subject, but it is simply a very sad thing, not only that there is this misinformation, but even more that it has made enemies and hurt businessess and caused such disruption, hand-wringing and rhetoric, unecessarily. Thus I refer to the "gotta use Viton or you're stupid" folks as Viton vatos, i.e. robots.
