G'day All

I am currently putting the pieces of a gf250s. I have a question about
the carbies, hopefully someone can put me straight.

I am wondering where to connect two possible hoses on each carby. The
picture in the manual just has the line going off to no-where.Its a
little hard to explain so I have posted the manual page into the photo
albums under the heading "help" The hose in question has been
highlighted red.
It appears that this hose was never connected on the bike, but as its
history is unknown I would love to get a confirmation before I put it
back together again.

The bike was running poorly and would not idle, could this be the problem?

thanks in advance
