An obvious question - Is the hand wheel engaged? Or was it loosened to fill a bobbin and not tightened back to normal? Is the needle in correctly. It should thread to left to right. If it's a drop in bobbin, is the thread all the way into the tension groove? Most have a slight click.

Thanks so much. My next questions is..... How do you get the bottom off to see underneath? Looks like I would have to pry it off. The bobbin race (think that's what it's called) does not move when I move the hand wheel. On my other machines it turns and that's what makes the thread loop so the needle thread can pull it up. As you can tell, I'm not mechanical and haven't the foggiest idea what parts are called.
Make sure you disconnect and unthread the machine first. You will need a screwdriver to unscrew the two bolts on top of your machine to take the top cover off. Take a look at the plastic nylon gear and see if there is any damage as you turn the hand wheel. Put back the cover and lets then check the timing belt as a second step. [ATTACH=CONFIG]302189[/ATTACH] [ATTACH=CONFIG]302190[/ATTACH] To get the bottom off unscrew the two bolts and the round button underneath. This will allow you to separate the bottom plastic from the sewing machine. [ATTACH=CONFIG]302191[/ATTACH] [ATTACH=CONFIG]302192[/ATTACH] [ATTACH=CONFIG]302193[/ATTACH] Then you will find a second metal bottom cover. Just unscrew the second part of the round button and the cover will come off. Inspect the timing belt and see what happens when you hand turn the two sprockets.

There are two upper gears one white on top and one black underneath. Make sure you check both...

OK, I was able to get into the top and I see nothing broken. Gears all look fine. Opened the bottom and it looks just like your picture. Timing belt intact. I'll try to attach a pix of the area I think is the problem. See the arrow? Nothing in that area moved when I use the hand wheel to raise and lower the needle. It is not disengaged for bobbin winding. On my other machines something in this area moves to make a loop for the needle thread. And the instruction book shows it threading from front to back.

Akkkkk - I actually did it!!!!

If the sprockets do not move then re-check the top gears as the bottom black one directly drives the right bottom sprocket. Let me know...

Pardon my ignorance but a sprocket would look like????? Upon closer examination, I found the bottom black gear crumbled when touched with a screwdriver. Is this something I can replace and where would I get one?
