A fellow came in to the Bike Shack on Sunday for work on his bike. Pretty standard stuff, but when we started to put his rear wheel in place I found that the rear derailleur's cage spring was pushing the cage _forward_ rather than pulling it back. I pulled a different old VGT from our box o' parts to get him back on the road, so I did not dig into the derailleur to figure out what was going on. I've found this old post:

Which has an exploded diagram showing the spring, and I also have had them apart in the past. Even so, I can't see a way for the derailleur to pull the cage in reverse. Has anyone seen anything like this?
If I have time later this week I'll pull the spring and take a look, but I will appreciate any hints on what to look for.
