Just an update here, I grabbed the plastic cap with some properly set vice grips and tried turning it and the nut inside turned with it, and it seems to be working better a little looser, I will take it apart and clean it out, when I do that bike in the spring, nice to know that I don't need to replace it or fool with the spring. It does sound gritty though, so I assume a good cleaning and fresh grease will have it working like new.... Not sure how well these single pivot side pulls worked when new, I have heard conflicting reports that they worked wonderfully and that they never did work properly, so I figure it's more and issue of getting them properly adjusted.
