I have a 7050 model JC Penney sewing machine. I can not thread the machine properly, because there are tiny loops appearing on the underside of the material being sewn? Help?

Question edited for clarity and better order.

The problem is that JC Penney were just a department store seller of machines made by someone else, a regular sewing machine company, ie Singer, Necchi, Nelco, Brother..., but was badged under JC Penney's name.

They make it with a strange plug that goes into the foot pedal. It looks like you have to buy it complete.

Unable to locate a manual specific for your machine, however, most machines thread the same way. More than likely, your machine was made for JC Penney, so if you could find out who the manufacturer was, you might be able to find a manual under the manufacturer's name, ie perhaps Singer, etc.

First Clean the upper thread path with unwaxed dental floss or some sturdy thin fabric like light weight denim. Get in between those tension discs and floss away. Then make sure you are threading the machine properly with the lever in the UP position and have a proper sized needle. (not all needles are alike) Make sure the needles you are using are not damaged or bent.

Go ahead and clean in and around the bobbin area. Make sure your bobbin is going in the correct direction in the bobbin case. (yes it makes a difference)

Do a test seam. Note any improvements... If you have loops on bottom... tighten the top tension. Loops on top.. tighten the bobbin case tension (look for tiny screw)

Do a test seam. Keep working the tensions until you get a balance stitch. Be patient... this sometimes takes a bit of time to get it right. Work mostly with the top tension if you can.

To determine if it is a timing issue, take off foot, throat plate and bobbin plate so you can really see. Use the hand wheel to get the needle to the lowest position. Note where the shuttle hook is... ideally it should be just about to pass the needle scarf at this point. If it is more than just a few millimeters away, it's out of time.

I can't help with with a manual for a JCP machine not sure where once could be found... would need more than just "JC Penney sewing machine to find one anyway... need model number."

there are some theading diagrams for JC Penny machines here http://www.sewusa.com/Sewing_Machine_Threading_Diagrams.htm
although your model is not listed. But take a look, often a make will have similar threading through several models and it may be enough to get you going.

Check the timing of the needle to the hook. Here is a guide to generic principles of Timing
