Singer 1120 Shuttle Hook Getting Stuck?

I was sewing on some sticky hook and loop (which I now realize was a mistake) and my needle got jammed. I got everything unstuck and put in a new needle. However now my hook will not turn properly. It is as though it is rubbing/getting stuck on hook cover. If take off the hook cover and hold the hook in place with my finger, it moves just fine. When I put on the cover and move the machine manually, there is a grinding noise and sometimes the hooks stops moving altogether, like it is caught. The needle seems to be in the correct spot and not rubbing so I didn't think it was a timing issue. Please help! Thanks.
