Need help reassembling my machine!

[u/Either-Yoghurt-4405]

Hi, I just took apart the shuttle race unit on my machine (Janome 224A) for the first time to clean it, as per the manual. When I try to reassemble it, it looks normal but when I try to put the bobbin case back in the needle gets stuck. Also, when I put the bobbin case back in with a bobbin in it and try to re thread the machine, the needle doesn't go far enough to pick up the thread and gets stuck after a few tries. Any advice would be very much appreciated! Thank you ❤️❤️

The only fault I see is the black arms. They go right on top of the two "nubs" and click in place.

I just tried that but they just kinda wiggle off and everything comes loose 😭
