Hello, How can I adjust my Mazda b2000 carburetor?

SOURCE: i need a vacuum diagram for a 1984 mazda b2000

I have the same problem. I was told that there are 5 or 6 vacuum line diagrams for the same truck. I called the Mazda dealer and they told me for $$$ per hr they would fix it for me. It was not worth there time to research something that old. I took that to mean that it is not on a dvd. Most likely a book , old shop manual. I have asked several people who own Mazda B2000 and most have replied that they removed most of the lines. And got it to run and forgot about it. I know this is not what you want to hear. But after a yr or so of looking that is what I have found.
