It may be cheaper to buy a new reel, unless you have a local place that will repair them. You can get a new one for ~ $30 +s/h * ... and I'd venture to say that most repair shops would charge close to that + shipping (both ways).
What, specifically, seems to be wrong with the reel ?? Some of our members may have these reels, and could guide you through how they corrected similar problems.
