The one with the visible spring is the idle stop screw and only sets the idle speed. The smaller of the 2 adjustment screws is an air bleed and will generally be closed off, it's there to lean out the idle mixture by bleeding air into the carburetor. This is to offset for a richer mix at idle speeds due to wear in the metering jet needle. The other adjustment screw is the main jet and is used to lean or richen the mixture for top loaded performance.
