pinkCastleDH,
Yes a bit. It works very good on my 201-2, but dismal on my HOTHER, a 15 clone. The stitch patterns are narrow but distinct on the 201 but on the HOTHER the ZZ pattern is narrow and the others is a bit wider.
The reason is the vertical stroke of the needle bar. The 201 has at least 1/4" more stroke than the HOTHER, and that affects the back and forth swing of the foot.
I haven't tried it on my Feather Weight yet.
