      My power valve in the barrel actually started sticking/seizing because I was using inferior 2T oil. It made the servo work overtime!
      I’d undo the centre screw and remove the cable rotor. Then check the servo to see if it sounds better without the load of the power valve on it. If it does try turning the valve by hand and seeing if it’s sticky or not…

      Whatever you do, I would definitely check it out…

          Taking the powervalve apart is pretty easy, you’d be surprised how gummed up it can get too. Always worth checking that out
