Mirage carb questions - 2

[tom3c75]

In addition to the T-junction balance tubes, each carb has another fuel tube that is open at the end and simply hangs down towards the crankcase.  I have not seen this before.  Is this arrangement correct, and what is the function of these tubes?

Looks like these tubes are connected to the vacuum take offs?, if they are and are open to atmosphere it will explain the hot starting issue.

The tubes connected to the vacuum take offs are fitted to the T-junction.   
It's the other tubes that are puzzling me.
Primary side carb has this tube on the right side of the carb and the centre and alternator side carbs have them on the left, alongside the vacuum take offs.

They are the floatbowl vents.
