Hi. I am looking for help please. I posted a few days ago about a 301 that belongs to a lady I have been working with. I was having problems with the bobbin hanging to upper thread and breaking it. It was suggested that I check for dust bunnies and burrs. I am not seeing dust bunnies and have some rust. I asked about removing the bobbin carrier and was told it came out from the top. The bobbin and bobbin holder are out but the feed thingys seem to be blocking the carrier. Do I remove the feed thingys and will the carrier come out easily. I am sorry to keep asking but it seems like a good machine if I can get it working. Or maybe I should just pay someone to fix it for me. I would prefer to do it myself so I will know. Thanks for any help.
