I have a Lew's bait caster, model CXPB1SHA Custom XP and have discovered that no matter how I adjust the tension knob and magnetic break, it makes no difference to how far I can cast the bait. The reel also makes what I can only describe as a bit of a buzzing sound on every cast. I can loosen the tension knob and decrease the magnetic break or tighten them both, no difference. The knobs turn and feel like they should be working. Any ideas?
