Thank you QuiltNan and Aborning I did call Chuck and he said to be sure to oil behind bobbin shuttle,on the back side, which I did again.I still have big skipped places.The only thing I have not done is a smaller needle, I am sewing cotton and one of my pieces and the backing is the same fabric, it is a tone on tone white but the print seems to have a thicker fill (it is a quilt shop fabric). Chuck said the size 16 needles I am using was great for this. But I will try a 14 tomorrow. Thank you all again.
