Well I bought a Singer quantum 2623 sewing machine for $20.00..I was so excited..Got it home and it sewed so good...I decided the change the needle but I couldn't get it out...I unscrewed the screw thing that tighten the needle all the way out but still wouldn't come out...I pulled and pulled and it finally did..I was so excited till I went to put another one in and couldn't get it to go in...I think what has happened is the screw thing has broken off in there? Just wonder if it could be fixed? Is there anyway to get the piece out? Thank for any help!
