On closer examination, it's pouring fuel out the driver's side main discharge nozzle. It's not even atomizing. Once I bring it off idle, the fuel flow matches the passenger side's and I start getting good atomization again. I didn't remove anything but the air horn. I lifted it just high enough to remove the pump plunger as I don't have access to the 1/32" drift required to remove the accelerator pump linkage. The truck is on a slight incline to the left, I may try putting it on level ground or a right incline. If the fuel problem changes banks or stops, I'll know it's the float. I didn't change anything there, but maybe.
