serger problems!

[pork-chop-girl.livejournal.com]

why is my serger doing this??? i thought i threaded it right, in the correct order, loopers first, and then needles. needle tension is at 4 and loopers are at 3. stitch length is at 2, and feed ratio is at 1. i cut out my pieces and sat down to get ready to sew and then THIS happened!! so frustrating. i need the stitch to look nice too because im making seams on the outside. i greatly appreciate any sort of advice!
