I've got a zebco omega issue. It has a "grinding / rough" noise and feel when reeling. But it's smooth as silk if I take the spinner head off.
I've replaced the spinner head with a new one, and the same issue. Nothing is wobbling, bent or out of whack, and I've cleaned and re-lubed everything.
I've compared it to other reels of the same model, and this is definitely atypical.
What could be causing this?
