I don't know much unless I see it. LOL I have a 2 year old grand son that would do some fun things to a machine too. Anytime he sees or hears a tool he is right there. Last night DH opened the hood of my car and looked - Wilbur got there so fast it wasn't funny. I shudder to think of that kid with a screw driver in hand or getting a hold of my Singer 319. I guess what I would do would be to open the throat plate, remove the bobbin and look - lift the machine and turn it in all directions - at least it isn't heavy. Use a little flash light and see if you can see that needle in there someplace - they will be to wedge in a tight place and jam things. It seems like that would be a logical start. I would have to go look at mine but I'm on the way out the door to pick up a $25 FW parts machine - well, we'll see. I wonder if there would be a picture of it on:
