Those carb bodies are "white metal, or pot metal" mostly a zinc, tin,
antimony, alloy. Not much aluminum present. It is not known for it's long
life or ability to be easily machined. It's main claim to fame is that it
is inexpensive and easily cast by automated machinery.
Soooooo, when you strip a thread in the float chamber which has been
exposed to crapahol gasoline for 30 years, odds are good that your efforts
to restore those threads will be in vain.
Better to find an unstripped one.
