The needle has a variety of clip positions that allow you to determine the position.
The higher the clip snaps into place of the needle, the deeper the clip is immersed in the mixer tube, and the thinner mix will be mixed.
If the needle is already at the lowest position and the mixing is too thick, you will need to choose a thick needle or a small mixer tube.
