if rotor loss, we add a reatarding system which consists of either F2 rasp bars bolted to the bottom, or lately we have good results from removing the access cage panel on the sep side, removing every other short helical and installing the rasps cross ways (horizontal) here in between the removed helicals. Shimming them 1_4" is even better. Secure with large washers and lock nuts through the square holes.
