Before I took this cylinder off I had it at 1 and quarter.  Quad was running perfect  on that setting,put it back on set everything back the same and it wouldn't close. I would run it wide open in 6th and end of the gear it would finally close with no top end power. I have 3 different springs tried them all no difference. It will only run decent at a half a turn. I m losing midrange from it closing it will not tune right. Either I lose some midrange or top end. The actuator  is super loose. I thought about rebuilding it with when I rebuilt the bottom end but it work fine then. When I had my other cylinder on it was doing the same thing to  but at the time I didn't know what was causing the problem. It has always worked on 1 turn or a little more. I guess it rebuild time with it. I m just wondering if their is one part in the actuator that goes bad or is it the whole thing.
