Reel repair

[cassidyta]

A buddy of mine asked me to look at a Quantum baitcaster reel for him. This is a lower end model and from what I could tell, he had submerged it at some point. I got it all apart and back together. Everything is greased and it appears to be working well now, except. The line guide sticks on the right hand side. It does not do it consistantly, but often enough to be a nuissance. It is acting as though it is jumping out of the grooves, but I can not be sure. Neither the pin nor the grooved bar show any signs of wear. I did have to get some rust off of both, but they look fine now.
Maybe I am over looking something simple. (Yes, I put the cap back on to hold the pin in place)

Any suggestions?
