Space out helicals by 1_4" or double stack them and install green stem helical package. Better yet would be install channel helical kit (bean kit). Do not install flat iron flow retarders or angle iron flow retarder that comes with bean kit. Install two more paddles on the end of rotor 90 degrees from the two that are there. Replace reverse cylinder bars with forward. If you have discharge beater that has rolled back leeding edge I would consider fabricating the newer straight paddles to fit your impeller so the impeller don't end up a bottle neck. You can do one or all of these but I would do helicals first. Good luck. Dan
