Recently serviced 2 avets, an sx and an mx. First time I used them, since servicing today - anyway to cut a long story short the anti-reverse seems to be giving some problems ie. it goes backways when under pressure making an annoying/worrying ratchety sound

Sure it is something simple I have done wrong, maybe the anti-reverse in backways ?? but wondering if anyone had any experience of this before I pull them apart again. On a plus note,apart form the above problem,both reels are working excellent thanks to the instructions here(Cheers Alan) and the ReelX has made a significant difference to the reel.
