I have a Janome 6260 that has a default needle position that goes to 3.5 every time the machine is turned on. I finally figured out (after a long frustrating year) that for what ever reason I have to have it on 4.5 to sew a 1/4 inch seam. I hadn't read the manual and had no idea of a default setting. I thought I was the one with a "default" for not being able to sew the 1/4 inch seam!
