I've tried to repair cracked carburetor castings with various materials.
None of them worked in the long term. Heat is the problem with most of
the epoxy repairs.

...Thanks for the update. If you know where the crack is and if all the
parts are there you could try to epoxy the crack with JB Weld.
Although I haven't tried it on really hot items, J-B Weld advertises
that their product withstands 600 degree temps and their testimonials
indicate that it hs been used to repair engine blocks. I have been able
to drill and tap the stuff---I think it would be worth a try.
