Where is the needle jet in a carburetor?
The needle jet—or nozzle as it’s sometimes called—is located in between the main jet and the carburetors venturi. Fuel comes through the main jet and into the needle jet. So the main jet does affect the needle, especially as the throttle opening increases. The needle is attached to the slide and slides up and down within the needle jet.

Where are the air and fuel screws located on a carburetor?

They work in opposite directions: an air screw controls the amount of air is being delivered (in is rich, out is lean) and a fuel screw controls the amount of fuel (in is lean, out is rich).

Why do carburetors have non-adjustable fluid needles?
Carburetors with adjustable fluid needles have notches to lower the clip (raise the needle) and increase fuel supplied. Carburetors with non-adjustable fluid needles benefit from the purchase of a jet kit (vs. buying individual jets) because most kits come with a replacement, adjustable needle.
