I've done a load of 360 carbs, 6mm seems a lot to adjust but I have seen tem with very low float levels. Are you set at 19mm or 21mm?
I saw a tutorial online that said to adjust to 16mm, is that too low?

You said the line had no fuel in it when you started, but it was full when you got back?  That's normal.  The float doesn't open until you start to drain it while running.  If you have the lines off, or just installed them, then they'll stay empty until you use some fuel.  If no fuel was going into the carb, then the tube would never fill up.

Truth.

Yes too low.  Like PJ said.  19 - 21.  I have mine at 19 he likes them at 21mm.  Anywhere in there will be a good place to start.

The fuel comes into carbs through the needle valve attached to the float.

Well one line filled with fuel and the other was empty when I first opened the pet cock. Then when I came back both had fuel, but the left only had fuel on the carb side, and the right had fuel only on the pet cock side.

Also, when I was riding, it accelerated really slowly. What would cause that?

Sorry I didn't know how to explain it correctly, but from my understanding the fuel on the far line isn't getting into the carb?

If the fuel line is touching the engine or close to touching.  It could be boiling the fuel inside the line. 
Cut lines as short as possible without kinking.  And make sure they dont touch anything.

fuel can boil at 90f degrees.  Boiling fuel will cause bubbles to form inside the lines.

I have heavy duty black fuel line w insulation sock on mine and heat shield under the tank.  To prevent this exact thing.

I think you got a stuck float/needle..it shoud have filled the vertical tube..
