This is an improvement on the purple foot which didn't work at all, I think because it was too far off the fabric sandwich. As soon as I wedge even anything under the bar to raise the presser foot, even a tiny smidge, then I get skipped stitches. I have ordered a metal open toe slant shank darning foot from sewing machine 221. When you talk about the Sew Classic one, do you mean the little plastic one that would require removing the last thread guide? I'll give that try if the metal one doesn't work.
I don't remove the thread guide as I've not found that necessary, but yes the plastic one that has a square opening.
Can you put on your regular foot and take a picture of it in the raised position? I wonder if your foot height has been messed with. You can release the foot pressure to see if that helps.
You can bend the arm a bit on that FMQing foot, but if you want to return it etc. you couldn't do that after tweaking it. I did tweak mine a bit but still prefer the plastic, square one.
Like I mentioned previously, I've had to reset the timing on many of my 301's for this very reason. Great with a straight stitch, but FMQing makes skips. But that's only after making sure it was out a smidge. I don't recommend you do it if you've not tried every other alternative or can't visually determine if the timing is out.
