Dax, You need to clean out those clutches. Even if they seem OK they can still get varnished up and cause minute alignment problems.
I think I mentioned before that you can get in there with a Q-tip, but the true way to get them perfect is to take them apart.
Unless you have been trained on how to do this, I reccomend that you do not attempt it. It can be tricky, and you can drop stuff behind the turret crown if you are not careful.
