The sealer in the threads is worse than if the threads were damaged!
The threads may be repaired by drilling, tapping, and using the next size thread, or simply machining a fitting with a slightly oversize thread.
The sealer will likely have clogged the idle jet, the idle passage, and who knows what all else.
When I was still restoring carbs, a carb that came in with sealer in any location (fuel inlet, gasket surfaces, etc.) to be restored got an automatic 2X on the price quote.
Sealer of any kind around a carburetor is for amateurs, or for sales folks hawking their wares!
