That's good, when I get stuff like that, I usually give it to my machinist. Not cheap, but he can save the part, where I might bodge it up, and ruin it. I'll usually try something, and then give it to him if my effort wasn't successful
One like that I had recently, the unthreaded tip protruding out into the air passageway was able to give me enough space to use a socket to force the tip back-outwards enough, that it fell-out the screwed side, which was drilled-out to the bottom of the threads, with no threads left holding it in-place. Chasing the threads gave me a functional carb body air bleed screw again. That one I was lucky. The next one, I just gave to the machinist. It had to be drilled-out.
