Thanks guys. I guess I have been reading too much into this. I know I must sound kind of pathetic, but I have never changed a chain on a bike before. What do I have to do to "adjust" it? I have a good Park tool chain breaking tool. I have got that far. I have not ordered the chain yet because I don't know what to get. Hyperglide or Uniglide compatible or any old six speed chain? Thanks again for all of your help so far. This has been driving me nuts trying to research and ID that freewheel and figure out how to get it off.
