:clapping:It was the tension possibly due to changing thread size. I made the adjustment and the stitches are perfect! Thank you all so much. I have saved this valuable information to my notes. Also, I agree I would prefer to have the full manual to this machine.

I did go from a 277 to 138 I will let you all know how it turns out. I can't thank you enough. I tried to load pics but they are to large. I did find a sample of what it looked like in the first article that was sent.

Nice! Not sure how to reply to each reply so will post here. Dirtclod that article on tension summed up what I have been trying to understand for years. I don't think it leaves anything to ponder and am very thankful that you shared it. JLSleather I had no idea the way the bobbin is loaded over vs under would make such a difference. I am thinking that might be the issue since it didn't happen until after I changed the bobbin. Only problem now is I have to resolve both the bobbin and the tension since I decided to adjust the tension in the midst of my frustration. Thank you both!

Hello I would appreciate any and all input. I recently purchased the 4200 and it seemed all was fine until I changed the bobbin. The top thread seems to be one long stitch with tiny loops holding it down. The bottom stitch looks just fine.
