That is a Mikuni chart, the air correction jet is the 'main air jet' noted up by the main jet. And of course you are correct that the effect of the air correction jet is felt mainly on the main jet, specifically at higher rpm, where too much air causes full throttle lean out. Amal carbs don't have an air correction jet to change.'slow air jet' is as mentioned the slow running air screw setting. Again, whilst the effect is similar between Amal and Mikuni slow running mixture screws, they aren't the same, one affects air flow, the other fuel flow.....screw one in....and the other one out.....go on, ask me if I can remember which is which on a casual Saturday afternoon!
