Take the thread completly off the machine and rethread it making sure it goes thru the tension wheel properly.
FYI Loops on the bottom-- Problem is in the threadding.. Loops on the top, problem is with the bobbin.

SOURCE: get everything threaded and when I go to sew it

Hello,
Here's some solutions to try.

* Re-thread your machine
It may be threaded incorrectly.

* Raise your feed dogs
If your machine has this feature.
* When you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting
caught in your machine.

I hope this helps you.

guide the the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)If it doesn't work like this, then there is probably thread stuck inside the tension assembly. Set the tension to zero and blow hard between the discs to dislodge the thread. If it passes this test, continue up through the take up lever,then down through the thread guides to the needle.
Check to be sure you have the correct bobbin and that it is inserted the correct way.
OR remove the needle plate to remove the bobbin case. Look for any burrs or rough spots. Use a fine emery stick and steel wool to remove and buff them Reassemble and try again.

Sounds like the timing is off. Take the bobbin out of the bobbin case and lower the needle into the needle plate. As the needle starts on the upswing, the hook should meet the needle just above the needle eye on most machines. If it isn't meeting at that point then your hook timing will need to be adjusted.

unscrew the black plate that holds in the bobbin case and move it over to the left just a little bit, but make sure there is still clearance between the lower right corner of the case and the plate. The case should be able to wiggle a little, but not so loose it can pop out..
