How long is the tube from the valve to the carboy? I'm thinking there isn't much drop if you measure from where the pickup tube end is at the bottom of the pot to the neck of the carboy.  Just for giggles & grins, try raising the BK up about a foot higher.  cheers!!!
If Homebrew & BBQ aren't the answer, then you're askin' the wrong questions... Cheers!!!

1)Use a hop taco(stopper) with your p/u tube where it is now(make sure to leave an inch or so space between the inlet and bottom of BK). Or 2) Change p/u tube to the periphery as Martin suggests. Height of BK is sufficient. Raising it won't help it drain better.

as long as the outlet is opening to air, the volumetric flow rate will not be affected by how high the kettle is. it is driven by how high the fluid level is in the kettle and will slow as the level drops.  the atmospheric pressure will be the same on both sides.  if the outlet is in the bottom of the carboy, as the carboy level increases and kettle level drops the flow rate will drop faster.

You said you tried it with water and it worked one time but not the other, from that I would say you have a bad ball valve. If you have water in your kettle and open the valve no mater what water should be coming out. The only thing to stop it would be the ball not turning.

+1 A more detailed explanation of what I was getting at. Thanks.
