Quoted from chrisnack:The brass eyelets looked good. I would guess it's the bar/spring assembly at the rear as from what I could tell that's what centers it. Once i cleaned it all up it worked out, but now it's not working again, I would imagine if i took Red out again, it would be dirty again or something.
It does center it, but the pressure is on those eyelets. Thenmetal could be fatigued. The torsion bar is easy to check. Remove a screw on one side that holds it in, and roll it. If it doesn't roll smooth, replace. local hobby store should have something similar for a buck or so, same for the eyelets
