Kenmore Model 1422 will not zig zag
Hello:
We have been given a Sears Kenmore zig zag machine Model 1422. It is in nice clean condition, sews straight stitch beautifully and we have the manual. We have followed instructions to the letter but it will not do any zig zag stitches. Is this a common problem with this machine or am I missing one little bit of detail in the instructions? Thank you for your suggestions.
