I was going to suggest the same thing. I am embarrassed to say how many years I was sewing & didn't know I should have my presser foot UP while threading through the tension discs, so the thread would seat well. I also didn't know where to adjust presser foot pressure.
With some of my older machines, I am not certain if there is a top or bottom to the bobbins or if it is universal (works either way). But of course there is significance to the rotation of the winding of the bobbin & which way you put it into the casing. Did you take the bobbin casing out? I have gotten a thread tangled down underneath before, & barely visible.
Best wishes with your machine.
I think everyone's advice seems just right.
