I have a consew 118 and I am having trouble with getting it to sew. When I got it the needle bar was striking the foot so I did a rough adjustment. When I first tried to sew it worked for about six inches then it started to jam. I bought a servo motor for it to make it run more manageable. Before I install it I have been trying to readjust the needle bar height and cycle it by hand. I can't seem to get it to sew again. There doesn't appear to be any way to adjust the hook timing so I'm not sure what to do.
