generally most sewing problems are due to sticking parts because of non usage as =you have stated or because the tension has been not set right. what I suggest is that you take the time to do some cleaning of the machine like what bis pointed out in your manual use a light weight mineral oil to wipe the moving parts with, but not too much. also adjust the tension of the foot so there is pressure on the material as to move it while sewing. after all the cleaning and adjusting rethread the bobbin and make sure it is seated properly also rethread the need and make sure the thread moves freely from the spool. this should do the trick. please rate this

I was hoping you would have got another answer, I have a mechanical sewing machine ( Singer 5040) with the exact same problem. However, if i use the programed stitches I can sew a zigzag. If i do it manually and set the zigzag width to any width ( even the widest) I get only the same straight stitch, and no mater what length I select it is the same too, very close to gether about 1 1/2 inch stitch.
I took my entire maching apart to expose inside both top side and underneath, nothing apeared loose or broke and i oiled it up. I bought a new bobbin holder and still the same effect. So it has to be something serious is my conclusion...sounds like a trip to Sears to me...LOL

In the center of the stitch length knob (at the right side of the machine) is a button. You would push that button in to get the machine to reverse.

Have you replaced the needle? Sometimes something that simple will solve the problem.
If you have changed the needle and rethreaded the machine, then take apart your bobbin and make certain there are no small pieces of thread or lint in it.
Check your tension. Do you have an automatic thread cutter? I had the same problem and it was because my automatic thread cutter was cutting the thread too short. Some how the cutter had gotten bent...I could not tell it, but it was.
To solve the problem i put the blade of a flat head screw driver under the cutter and GENTLY bent it back down. Fixed the problem. Works perfectly.
some machines can get "out of time"...the needle and the bobbin thread don't arrive at the right place at the same time.In this case you need to take your machine to a repair shop for re-timing
