I called the local AGCO dealer this morning looking for a carb bowl gasket and a sediment bowl screen and gasket.  He said none of those parts are available anymore.

So I called up Case and asked for the parts from a Super C.  They used 2 different Carter carbs on the super C and the parts guy led me through Case's website with parts diagrams.  I found the one that looks like mine, and they have the gasket in stock.  Unfortunetly the choke butterfly is a &quot;retired&quot; item that is no longer available.  He searched all the dealers in the nation for me for a NOS part, but no avail.

Thanks John.  Letting me know about the Super C carb has helped me greatly.
