White metal isn't archival like bronze, brass and copper. There are many variations in alloy and some last better than others, but they are all subject to attack to one degree or another by moisture which of course, when it accumulates in the fuel, lays in the bottom of the float chamber and whatever lower recesses it can get to, and that's where the gradual deterioration starts.

If you wanted to "tin" just a tiny portion of the thread or area where the plug goes and are reluctant to try the JB Weld and mold release method, you might try "Rose Metal", a compatible alloy that melts about at the boiling point of water. Readily available from gunsmithing supply houses. But due to the low boiling point you only want it to fill pits or put the thinnest of layers on damaged threads where the larger mass of the carburetor will act as a heat sink and keep it from remelting.

Assuming teflon tape doesn't work, that and the mold release agent and JB Weld are my best suggestions.
