I am fixing a Chevy Van 30 Motorhome, year 1978. Currently, most of the problem seems to be of the carburetor. I believe I am missing link between the parts that control the air and fuel ports for opening, on the top of the carburetor (the open and close flaps).

If any could please give a stock diagram or picture(s) of this carburetor, it would be most vital.

thanks for everything

Here is an exploded view. Please only use this as a reference. They would change things. If you need to rebuild it, the part number from the carb will be needed.
