You have to loosen the CAS on the back of the head and rotate it. Do it in tiny amounts and check your timing after each move.

Read the timing section. Should pretty much apply to you.

Before you loosen the retaining bolt, use a scribe to mark a line across the body of the CAS and the cap at the back of the head which it abuts. This was you have a reference point for where it was before you started. (I'm assuming purely from the tenor of the conversation that you do not own a timing light.)
