75 GL1000 Carb Question

On the inside of each carb before the butterfly valve there is a small brass colored periscope with a tiny hole in it. What is the function of this.

I wish I could remember.????It's been 10 or more years...
with a tiny hole,there's only a few possibilities..mid range fuel supply, air metering for the air cutoff valves or a bypass air circuit to the upper slide chamber...
Stick it and force fluid through and see where it comes out...

That is the pilot outlet nozzle. The passage below it goes directly to the pilot screw. Idle air/fuel mixture.

What dingdong said. They can be cleaned in place. No need to press it out and take a chance of breaking them.
