-There’s a lever for the presser foot pressure, turn it to “1”.
-On that piece the lever is on to the rear, there’s also a white plastic flat head screw, turn it and that will release that side cover. (You’ll kind of still need to pry it off, it seemed a bit like I was going to break the plastic, but it comes off).
-Once it’s off and the inside part of the needle bar is exposed, turn the handwheel until the needle bar is at its top dead center position, revealing a smaller flathead screw that will be just above the light.
-Either tighten or loosen that screw to move the needle bar to correct height, which leaves exactly 11.5mm between the tip of the over-edge needle B and the top edge of the needle plate. I put an arrow on the pic I posted of where the screw I’m talking about is.
Hopefully that helps someone and makes sense.
