If you remove the filter assembly, you will se a round hole with a disc on it. The disc moves down when air passes by. The longer down it moves the more fuel gets squirted into engine.
If this "disc" get stuck the fuel injection will keep squirting same amount of fuel into engine regardless of throttle position.

The plunger is kept from being fully depressed by pressure difference between "control pressure" and "system pressure". Thus it's important to measure these things in order to troubleshoot CIS fuel system. There are many posts on Pelican Parts covering this issue.
