Chironex spartan 500 carb hose question

[Pnut Butter]

does anyone know what/where this hose get connected to. is it a vacuum or vent... engine run but when given throttle it tends to bog or die out. if i blow a steady stream of air in it engine throttle responds perfect.

It  helps tremendously  if you  say what  machine the carb is used on.  A quick search on the  net  should bring up   pictures of the carb in use on your  machine  and where the hose connects.

I found an  owners manual  and a service manual  for the  CFMoto 500 and  uploaded them to  the downloads section of the forum.. That  hose  appears to  be the  carb diaphragm  vent  hose in the service manual.  I don't see it   illustrated connected anywhere , but I'd guess it  could be connected to the air box.
