This may be the person that has been looking all over the Internet for
such a diagram for months. He never identifies exactly what he has or
whether it might be modified. If my car has an automatic choke I can
find it because it has to have a choke plate in the airstream
somewhere. My sense is that he is stuck in the past and looking for
something because it "feels" like a choke not opening. He could have
something more modern with a bad throttle kicker that gives him that
feel. OH well, ignorance is bliss. Have a great day Stephen.
