Help me with my Baughman Recliner...  

My Baughman recliner, which I love, has taken on an interesting problem with the mechanism.  Stage 1 seems to work just fine; the footrest pops up as it should and the seatback moves back a notch.  When I try and push the seatback back for Stage 2, the thing leans to one side and only the right side lifts up.  The way it should work is that the back tilts back evenly and the seat lifts up in a level way.This has me stumped.  I even have a 2nd matching recliner and I've taken long, hard looks at the mechanisms in action and just can't figure it out.I'm hoping there's someone on here who is handy with reclining mechanisms, or who has encountered this issue before.  Unfortunately it's out of warranty and I'm hoping I can fix it myself before going through the effort of finding and bringing it to a furniture repair place (which I will no doubt find without a reference, through Yelp).Please let me know if I can provide any additional detail or context.Thanks!!Alex
