Hi all. I recently noticed the bypass on my Revere is starting to stick when I pull it open at about 3/4 of the way. I really have to yank on it to get it all the way open, and closed again. Anyone have this happen or have any suggestions how to fix it? The insert is a 2010 had has not had any unusual pressure put on the bypass to possibly bend it. There has been no over-firing either. Thanks for any suggestions...
