How can I have a richer carb on high without changing it on low? (Yes, it’s my preparer work but I’d like to know also yours thoughts)

Transition jetting as it’s called is typically handled by adjusting the needle and clip

I’m doing a clean of my carburettor for Rotax senior max and I’m trying to identify what these two particular screws are called. I keep hearing people referring to them in different names. What’s A called What’s B called Is one like low and high speed idle adjustment? [IMG_20200715_012839~2]
