What is a bobbin? and I think its threaded but the needle isn't moving

Here is a link to get the instruction manual for your machine - sorry couldn't find one for free but it sounds like you could use it; http://www.sew4less.com/product_details.php?ProductID=4196 a bobbin is a reel on which thread is wound, there are two - one on top and one below the footplate and fabric dogs. If you are struggling with the terminology then read the manual for threading instructions as it is not necessarily as obvious as it looks and is difficult to describe without a picture unless you know the names of all the parts around which the thread has to pass. The pedal not operating could be due to numerous reasons - please post back if the manual doesn't get you started and let me know if it has ever worked, if so what were the circumstances when it stopped working. Sometimes if a machine hasn't been used for a long time and hasn't been properly oiled/serviced (very important), you will need to start the machine sewing by hand before the motor will kick in - if that doesn't work then you probably have: 1. A faulty pedal (often the large value capacitor in these goes and is simple enough to replace if you can solder. possibly other parts although these usually fail gradually) 2. A faulty or incorrectly attached cable to the machine. 3. A faulty power plug or cable or socket or fuse if it is fused 4. Faulty settings on the machine (especially if some controls are not quite in position) 5. A faulty motor (fairly easy to repair, probably requires some spares) usually you would get some more indication of this than just not working like noise / burning/ smoke/ or working a bit but not properly. 6. Some models also have a fuse or thermal reset switch in the machine itself, couldn't get that info for sure without the manual but it is worth a check. Hope this helps - if you don't want to pay for a manual then please ask again with more details of the problem and photos of how you have it currently set up, and hopefully I can help :)
