Ok, let's eliminate or verify the spool,
-Wind the line tightly and tape down with some painters tape (scotch will work in a pinch), or remove line. (make sure nothing is protruding or touching).
-Loosen tension knob until you have a very slight play, and set the brake to lowest setting.
-press the thumb bar, hold the reel level, and in a quiet area spin the spool with your finger.
If the spindle is bent, or something else is getting hung up, it will be obvious. If it passes this test, then move on to the drive train, instructions available to Patrions...
