SOURCE: need a sewing manual

I did a search and found a site that sell the manual you are looking for. I'm including a link: http://www.sewusa.com/Sewing_Machine_Manua/kenmore_Sewing_Machines_117_120_Models.htm.

I found it on Google buy searching for Kenmore sewing machine manuals.

Hope this helps. Ginny

SOURCE: needle does not pick up bobbin thread on my 373

Are you certain that the needle is in correctly? If it opens at the front the flat side of the needle should be facing the back. If it opens on the left hand side then the flat part of the needle should be facing into the body of the machine. If top and bottom are threaded correctly and the needle is in properly and fully in position it should pick up. If it doesnt then you "could" have a timing fault.
