I remembered reading somewhere that size 14 needles were the most common needle size used in the past, so vintage sewing machines were designed to work best with that size. I can tell you that my Singer 328 skips stitches like crazy on knits unless I use a size 14 needle, regardless of the fabric weight. Different sized needles are slightly different lengths, so I just thought it was worth a try.
