Greetings Fartman22!

I personally always adjust valve clearances with the engine not running. In fact, most owners manuals suggest making the adjustment with the engine not running, since it is extremely difficult to get an accurate adjusment when moving parts are involved. Side note-some adjusments are made with the engine cold, and other manufacturers require that the valves be adjusted after the engine has reached operating temperature.
