There should be no need for shims, they would harm perfromance and I'm not even sure where they would even put them. The Karousel inner platter is the same as the Cirkus one but the bearing housing and inner platter should always be replaced as a pair. Also the Karousel requires a specific torque to give the most musical perfromance. Linn recommends 3.5Nm which is close although I found 3.4Nm to be more musical as you can read elsewhere on the forum. But the point is that the Karousel should not be installed without a torque driver in the proper range. I have found it to be quite sensitive to torque and Linn cautions against torquing above 4.0Nm. If this torque is not right the LP12 will not perform as it should.
The more I hear about this dealer the less thrilled I am about them. I hope they can get this straightened out for you. Good luck with it.
I took some pictures, don't know how relevant they are, but, is normal to have this "dents"?
Sorry, maybe I'm becoming annoying, but I started do doubt everything.
It seems to me that he hasn't used the right tools to have the Karousel mounted.
