This morning I decided to clean and oil my featherweight. I removed the throat plate to check for lint. Put the throat plate back on. Now my bobbin tension isn't working! the bobbin thread is getting picked up but it's not sewing properly. I've rethreaded both the bobbin and top many times. I've replaced the needle...still not sewing right. What did I do wrong? It was sewing like a top before I started??
