On the bird 43 line sections they have that little clip that turns to hold the slug in place. One of mine is really tight, to where i have to us a small screwdriver to pry it open on top the little pad. Is there a way to adjust the tension on this clip? Its clean and the spring is in new condition so its not sticky/dirty or anything. Its just way to tight to open by hand. Closing it is smooth with no problem.
