Just bought a Kenmore 117.740 in cabinet at a thrift store for $7! It works but there is an issue with the zigzag gears. That's ok because even though I will get it fixed eventually, I got it for straight stitching. It came with all the tools, feet, bobbins and even never opened packages of needles but no manual. I need to find a threading diagram for it. I found information on oiling it and while there are manuals to purchase I can't afford to do that right now. I will hopefully be getting photos of it up soon. If anyone could help with the threading (and winding the bobbin) I would greatly appreciate it.
