But it is frustratingly difficult to separate the shims from the tops of the followers. I had to use the point of a utility knife to separate the shims at those little notches cut into the top rims of the follower cups to get them off.

So you can imagine how difficult it might be to remove the shim using the tool that compresses the follower to supposedly allow you to remove the shim?? This is why I simply remove the cam; I find it much easier to do it that way.

You can use a micrometer to measure those shims you scored and hopefully you will have the ones you need for any adjustments.
