Carb leaking?

Hi,

I'm a bit confused at the moment. I'm rebuilding a sportster and after fixing the fuel elbow in my last post the carb etc. Seemed to work fine.

Today I wanted to continue the build but noticed a leak on my carb.

Last thing I did was switching to another petcock because I wanted to see if it would fit better. The old petcock had an opening for voes ( which I run at the moment), the new one doesn't. I'll order one with the voes opening, but first I had to make sure the petcock style would fit. So my question is : is this the reason for the carb leakage ( pulling air by the opening so fuel just runs though?) or could it be something else?

Another thing regarding the carb : where did you route your overflow(?) line ( 2nd Pic)?

And last thing : do you run the voes or did you throw it out? Reasons? I run a dyna2000i so I guess I could get rid of it pretty easily.
