My AAR does this also if I let it sit too long. The bowels dry out, the floats drop and the needles fall down causing the floats not rise when fuel is pumped in. This allows raw fuel to be pumped into the carb bores. You can see this if you remove the A/C, run the car for a few minutes, shut it off and look down the bores for fuel dripping. If it is back off the needle and seat until the float rises and then reinstall the needle and seat.
