No that's not normal. Sounds like you need to adjust your float height. Hopefully you've got a clymers on ya or somebody can chime in with the specs. Basically that little tab we were talking about, well you gotta bend it a c-hair at a time to make the float height change. Hehe...its pretty much trial and error - bend a little, reinstall floats and measure, bend it back cuz u went to far, etc etc...
Oh ya and if that's not enough, you might need to rejet since lowering the level in the bowl is gonna make you run leaner.
