I once had to do a simalar fix on a Mikuni (sp) Carb. I though it was
Aluminum, and tried to use one of those Alumi Rods (the ones that use
a propane torch) I as soon as the torch touched the carb it melted ...

It was a thin section , but the propane torch wasnt even on it 5
seconds. I dont think I could melt aluminum with a propane torch that
quick. 

Now this was from a motorcycle. I dont know if that makes much
difference.

I believe most carb bodies are a zinc alloy. I hate to admit it,
but I've repaired several worn throttle shaft bores with good old
JB Weld.

Some carburetors are aluminum, such as the Carter AFB (Aluminum Four
Barrel). But others are zinc castings, such as Rochester Quadrajets.So I
guess the answer is, "It depends". Several others have cast iron bases
(for use with heated manifolds) and zinc float bowls. And the Carter
Thermo-Quad has an aluminum base and a phenolic float bowl (reduces heat
transfer to the fuel to limit vapor lock and evaporative emissions).

Welding it up might be interesting..  I threw one into a fire once to melt
it down, turned out to be a magnesium alloy.
