There is a place on the motor where there's a little spring is sticking up. Will that bother the machine? What do I need to ask for to get it fixed? There was a screw top that fits the area, but won't fasten down on it. And the side plate bobbin cover needs the spring and the screw to fasten it down. Other than that the little machine just clicks along so nicely and is a joy to sew with. Thanks.
