His suggestion was to place (2) 1/8" large area washers behind the two upper engine mounts, then fit your cowl to the spinner. After x flight hours when the engine has sagged 1/8", remove one washer from each upper mount. Remove the second washer after the next 1/8" sag. He said it is quite a bit more trouble to try and fix the problem by adding shims to the bottom mounts. For those of you with the newer and supposedly softer mounts, would you expect the engine to develop a sag of 1/4" total or perhaps even more? Also, do you know the manufacturer and part number for these newer style mounts?
