That's actually good news. It at least confirms several things. 1/8 NPT is correct and the non donor threads are "screwed". So find a good top from Carb King or Mike's carburetor or Ebay or wherever......to start with. Then drive and observe.
"I loving fixing old things folks thought could not be rehabilitated.".... we all feel that way here. This is not a case for that. Carbs are too important. Leaks are too dangerous. Carbs are too soft to fix important treads. JB weld and all that jazz is no good. Donor carbs or pieces are cheap. It's too easy to replace it right and too hard to fix it right. Put an ad here in "wanted". Lot's of guys have good parts. This is AD Land.
THIS is a "Make Offer", free ship.
Not telling you what to do, just one avenue.
