      I started on the carb today on the A-80.
      Everything was going okay until I got
      to the fuel inlet nut. It doesn’t want
      to budge.
      So far I’ve heated it with a bottle torch,
      doused with WD-39-1/2, and laid a nut
      flat on the vise while I smacked the other
      side with a hammer. The repeated it all,
      and still no luck.
      In the process, I managed to bend the float
      needle and break it off, at it’s thin spot
      where the float clip goes. 😯

      Q. Are these inlet nuts usually problematic?

      Q. Normal "right hand" threads?

      Q. What’s up with the fuel line being soldered
      onto (or in my case, it looks "gobbed on")
      the inlet fitting? Is that factory?

      Q. Will I be able to borrow a float valve from
      a more modern carb?
      I can’t get the broken float valve out until
      the fuel inlet nut comes loose. 🙁

        The thread on inlet nut is standard right hand. Mine was very tight too t it did come loose, it should have a paper washer in it, mine did not so it was metal on metal, not good.
        The fuel line is soldered at that joint from the factory, some are better than others and many have been repaired, poorly. It gets loose over time from removing the tank and flexing the line.
        As far as using a new float, if you can find one to fit it would be fine.

          Bye the way, your float I. The pic does not look bad, just use it you’ll be fine. Avoid the ethanol gas.
