well, if your gasket is in place like it should be, and if you used a very small amount of sealant on the mating surfaces, and..... if you used some blue loc-tite on the bolt threads, there should be no leaks. are you sure the gas isnt dripping or seeping from the carb somewhere higher up? i would think if you had a leak there that the engine would have running issues such as poor idle and stalling on acceleration. and plug chops would indicate a lean situation. so if you remove the reed cage, and use a straight edge to ensure its not warped, then reseal everything, you should be ok. but i would look very closely at the carb first.
