GPZ1100 Carbs leaking.

Hi All. 
My '82 GPZ1100 started peeing fuel out of the #2 carb. It comes out of the bottom drain when the engine is running.
Only started on the way home last night. Could it be the throttle slide that is stuck?
Thought I'd get some feedback
before I started stripping it in case I needed to order any parts.
