Yes, the combination of CLEANING that bobbin area (recently, I removed over a tablespoon of chunky gunk from a bulking New Home) oil, movement and heat can make a huge difference. Sometimes PBlaster (spray penetrating oil) has its place.
Instead of insisting something move, PBlaster and an hour of soaking in the sun can keep metal from being bent. Yes! After applying oil turn it all around! Gravity can be quite handy.
