I'm watching your Singer 319 stitch issues conversation with great interest. I still have more to do to get mine to work. I've been really busy on other things and other machines lately. Yesterday I got a lot done so I'm down to just a couple machines. Mr. Ed (319) has gone back up to the top of the repair line! I have needles now but I forgot to order a belt. I have a hand crank so I may test that out on it. I'm pretty sure I'm going to be sitting there with the manual in one hand trying to figure out the bite thing since I turned it. I found another 319 on CL but they don't have contact info and don't answer emails. Maybe it is sold and they haven't taken it down.
