The brass tube will be used to run a Tygon 1/8" tube into the fuze. This eliminates the problem caused by changing pressures inside the cowl due to airspeed changes.
To do this, remove the cover from the carb, scuff the area to be soldered with emery paper and solder the brass tube to it. If you are not familiar with soldering, do some research online or get somebody to do it for you.
You can also see how to do your carb linkages.
