Ed,
Here you GO.
Now remove the cooling head and head button. Fit the .2 mm brass shim which came in the box with your motor. This is the "break in shim", and it is used to lower the compression on your motor, making it easier to start and run during the break in process. Make a note of where you fitted this shim, as you will be removing it after initial break in. Replace the head button and cooling head, making sure you nip up the head bolts in a cross pattern to ensure even tightening down of the head.
