Carter 750 float level

Rather than start a new thread, figured I'd just bring this one back around again. Why would I have fuel down in the secondary counterweight wells? Same Carter 750 AFB, the floats are set parallel after switching to solid needles, and I'm using a Holley blue pump with a dead-head regulator set to 5 psi. I noticed it after trying to start the car (this thing's still kicking my ***, I can almost write a novel about what I've done so far), so I ran the pump twice today but haven't seen any fuel pooling up yet...and there's none dripping down into the manifold if that matters. I have 3 other engines with 625 AFBs, checked them all, none seem to have this issue. They have mechanical pumps on them, however.
