I told a friend I'd look over her Kenmore which is doing something odd. When you sew a while in zigzag and then switch over to straight stitch, it continues zigzaging for about an inch or more, then straightens out.

I haven't worked on one of these before, any ideas what's wrong? I'm guessing there's a built-in cam stack and it isn't fully switching over when the selection knob is turned.

Any help will be appreciated. Oh, and does anyone have any tips for easily removing the plastic shell? I always feel like I'm going to snap off something inside because they don't separate without a struggle.
