Friday I took my CU100B Shimano Curado apart and oiled/lubed it. I put it back together and everything was alright (I thought). I used my heavier stuff over the weekend in the salt and today when I went after bass with the Curado, the thumb-bar wouldn't go down and disengage the spool ( read: NO FREESPOOL). ;( I don't have a parts diagram for the CU100B but I do have one for a CU200. Tight lines, Wade
