What do these do on the carb?

See in the attached photo, theres obviously 4 butterfly valves which open when throttle is opened. But in between each pair of openings is a screw with a spring.... theres 3 altogether. 1 between first 2 butterflies, 1 between next 2 etc. Are they idle adjusters?
Reason i ask is one of those screws on my bike is missing its spring, and either that is the reason for its erratic idle,.... or the butterfly is slightly sticking. Because the minute you adjust those springs, the idle drops, and will also fly up if you adjust them the wrong way too much
So im curious is it the missing spring causing an issue, or perhaps a sticky butterfly valve.
Everything else on the bike is sorted now. All jets, floats, needles, etc etc cleaned and all fuel lines cleared and cleaned.
