I picked up this machine for $15 today at a yard sale. No manual. It looks brand new and sewed fine until I put in a new needle. Now it won't sew a stitch. I put the old needle in and it sews. Only problem the old needle is dull. The old needle is much longer than the new Schmetz universal needle I'm using. anyone have the manual for this machine to tell me the needle recommended? I have a Janome Gem and use the regular Schmetz needles in it all the time.
