When testing the float level on a wooden jig and scribing the .020 and .017 on the side of the bowls and gauging with the meniscus method, I applied slight air pressure to the hoses and saw much weeping around the float gasket. When I removed it and put it to a flat surface it was like a teeter tater rocking on the screw ears.
It finally dawned on me that your question may be about the seal of the gas side of the pilot circuit at the gasket and not anything about the venting of the bowl at all? Could you describe the setup you used for checking fuel level? When you pressurized the hoses was gas coming out of the pilot orifices, needle jet, and tickler too?
I mounted the carb on a wooden platform vertically, hook a hose the inlet of the carb and a hose to the drain plug via a nylon elbow. I raised the drain line along side of the carb to act as a site glass to see the level. On the inlet side I hooked a weed sprayer and applied just enough pressure to keep the hose filled as it demanded(just a pump or two). I drilled a small hole in the drain hose to simulate usage. As it would empty I could watch the level drop then the sudden rise to the required level as the float activated.
I blew on the drainhose (not sure why) at some point at which point I saw fluid and bubbling coming from the float bowl/body gasket. Hence the posting. Although fluid would come out of other places(tickler) my concern was for the float bowl area and pilot circuitry due to the warped ears.
