more recon problems

so I rebuilt the carb, and like you guys said, very simple, however, she still cuts out when stood up. it shuts off then won't start back up for about a minute. I have the fuel idle and everything set perfect, I can't figure it out. When it stands up fuel pours out of the vent line does this mean I am flooding out? if so what causes this? I took the tank off and cleaned the filter also, so I am lost. thanks
