Sewing machine help Please! Again!
 

Does anyone have a singer quantum 2623 sewing machine? I found one at a thrift shop for $20.00. It runs good but is slow? Can't find a place where you can control speed..was just wondering if it just runs slow? Trying to get it to do fmq.and it is so slow!! Just wondered it there is a way to speed up a machine? Thanks!
