Holley 770 Street Avenger Bowl Drainage Overnight!

Well, I went to the engine builder today with the power valve and it checked fine. I got back home and put everything back together, filled it with fuel and put it back on the bench. Fuel is still leaking from the baseplate. I took the whole carb in to my builder and he says everything is adjusted good...floats, acc pump, etc and he has never seen anything like this from a Holley. He thinks that a metering block may have got drilled too deep or there is a crack internally causing it to leak out. I called Summit racing today and they are going to replace the carb for me since it is still brand new. I will box this one up and get it shipped out tomorrow. Then it is a waiting game for a new one to show up. Thank you all for the advice.
