Need help with my New Singer 4411 Sewing Machines Parts and Sales in Los Angeles

Hi Everyone! Sorry if this is not allowed. Though I’m running out of ideas and needed experienced sewer to help me. I have sew may be less than 5 times in my life and I just brought a new 4411 over the Holidays!

As a beginner, I’m very excited to do something. Yesterday, I pull the machine out due to snow and after some starts and stops, I was able to hem my dress. ( low quality thread and unable to thread my bobbins.) Today, I am sewing swimwear fabric on to a bra to make a bikini top. I change the needle to a ball point and quality coats thread. Then off I go! My machine has skip some stitches, but after taking my thread plate off, I have found the bobbin black thing is not seated right. So I have fixed that. I finished one side of the cup with no issues. Then I started on the other side. Then I felt the machine slowing down comparing to the other side and I have tried hand turning and I have felt more resistant then before. So I took the cover off of the needle arm portion to see if there is anything that’s in it’s way. There is nothing. No Dust. No thread. Nothing. Then I took the needle plate off and find the black part of the bobbins is off of it’s housing. I will post some pictures, in the links. It is very frustrating stopping mid project and fixed the bobbin piece. Did I screw it up or did I get a lemon? Thank you in advance.

Mods – if this is not allowed, please let me know where I can get help on this.
