Joyce, I picked up my machine today. Mine is a 1681 so it's a little different. I'm going to keep it as it's not as bad as I remembered it being and it works. The lever knobs on mine are falling apart so I wouldn't be able to help you there anyway. Sorry I can't help you. BTW, for those who don't know, these machines were made in Korea in the 1980s.
