A piece of crap is lodged in the needle and seat or the assembly is bad.

One of these or a combo is probably your problem. Float needle or seat is leaking, the Oring around the needle and seat assembly could be cut or rotted, the float could be bad and getting fuel inside, your regulator could be set to high, if the regulator is a dead head type and doesnt return back to tank it could be creaping and fuel psi bucking the needle and seat. You can tie in a psi guage to check the last one.

Most likely you're needle has crap in it. I know I installed brand new needle valves only to find one bowl overflowing. When I removed the new needle again I noticed that the little o-ring had severed and a piece was stuck in the needle valve. This occurred because I was not careful enough when installing the valve. Back the guy out and if there's nothing in it (use the blowgun on your compressor to really clean it out) then check the o-ring.
