Rivka,
I was wondering if you've gotten your replacement regulator from Mr. Bailey yet? How is it working for you?
I just received my 17 today with the sew control and haven't tired it out yet but after reading the meager instructions that came with it, it specifically said that the slower you set the controller the larger and further apart the stitches would be. This is NOT what I was expecting either and I'm tempted to just return it. I want the regulator to control the speed and the stitch size. Hope you see this message and can reply. Thanks!
