Fresh rebuild leaking like a sieve

Hey all, been doing some reading on this issue, but haven't nailed down anything definitive. I just rebuilt my carbs, ear shaved, rejetted, etc. Everything rubber was replaced, o-rings, diaphragms, fuel lines. Got the bike running, and now my carbs are leaking like crazy. It looks like the leak is coming from the float bowls. When I rebuilt the carbs I did not replace the needle valves as the rubber still felt great, nice and sharp. One thing I'm seeing in some of the rebuild threads that I totally missed and neglected to do was to adjust the floats. Could this be what is causing the leak, or is there some other stupid mistake I could have made?

Other than not replacing the needle valves and seats?

Float height could be the culprit, either way looks like you'll need to yank the cabs again..

Floats could be stuck, sometimes firmly rapping the carb bowl with a plastic screwdriver handle can free them.

Always shake the float when it's removed to be sure it hasn't filled with gas.
