do any of you know if there is a bike shop that makes house calls?
I've not used him but he posts to FB

I know it can be frustrating. My suggestion is to substitute another wheel and see what happens.
Also, you could join
Home - Sumter Landing Bicycle Club, show up at a regularly scheduled ride (Barnes and Nobles or Bradenton Rec.), introduce yourself, ask around.
They are really friendly folks, knowledgeable, and always happy to help a fellow cyclist.
