Looks to me that carb adapter was attached BEFORE the metal piece to the left (generator body?).
If that part to the left is the gen body, then I suspect the gen body WILL have to be separated from the engine before the carb adapter will ever come off the studs..
If the carb adapter is aluminum, you could have a new "ear" fabricated and welded on if you can find a welding/fab shop that specializes in in aluminum fab and repair..
If pot metal (zinc) you are out of luck, pot metal doesn't weld..
Doubt it is cast iron, pretty obsolete now days, welding cast iron is tricky, can be done but temps must be controlled to do it properly..
If nothing else, fabricate a bracket that you can bolt to the backside of the adapter (where the cast in PN info is)..
