Your main jet alone controls the fuel delivery from 75% to 100% , you should try various sizes to see what size works best for you .
From 25% to 75% the mixture is controlled by the needle in conjunction with the main jet that you had previously chosen . Lowering the needle leans the mixture , raising the needle enriches the mixture . If you later need to change the main jet size you will need to do the needle again . To answer your question the needle acts like a cork for the main jet , it lets a little or a little more gas pass by .
From 0 to 25% you depend on the pilot jet , this mixture is adjutable with the idle mixture screw and the tool ( if you have one ) .
