In an effort to maintain and better understand my equipment, I took apart my Daiwa Tatula 100HSL baitcaster (it didn't seem as smooth as it had been).

Anyway, now when I put it back together, it will reel relatively smoothly if the drag is very loose, but if I tighten the drag it is difficult to reel (and a portion of the rotation is more difficult than the rest).

Any suggestions as to what boneheaded thing I did might cause that?
