Anyone have a Huskylock 905 Serger? I absolutely love mine! I noticed this week that when I'm changing the thread that the lower looper eyes don't line up directly. When I push the tab to align them, it doesn't move the front eye over as much. I'm thinking the cotter pin is coming loose. Has anyone else ever had this happen?

I can still thread the lower looper, though it takes me an extra moment to pass the thread through both eyes. (Now really, doesn't that sound painful? LOL) Thanks for any comments you can give. Happy Sewing!
