If one were really desperate and you had an old carburetor carcass to practice on, you might want to try a technique from the gunsmithing trade used to "bed" steel actions to wood stocks for a perfect, intimate fit. It depends on using "JB Weld" 2-part epoxy which I believe is gasoline resistant.

The method depends critically on the use of a "mold release" agent which is usually an aqueous polyvinyl alcohol solution. Apply the mold release agent to the brass passage plug screw and then apply a THIN film of JB Weld to the damaged threads and plug screw seat, and screw them together. After the JB weld has cured, if you applied the mold release agent carefully the two should be come apart again and the threads will be "repaired" and the fit will be restored and should hold gasoline.
