idle volume screw

So I have a 32/36 DGEV weber is there such a device on my carb called a idle volume screw / idle speed screw or are they the same thing.

I would guess they are the same. Maybe there is a lingo that calls the idle speed screw, the idle air volume screw, shortened to idle volume screw?

There are two types of screws that are common on carburetors...
Common names for them are idle mixture screw(usually 1 per barrel), located on the main body of the carburetor, and idle speed screw, located at or near the throttle linkage.
