 It can be valve adjustment. If the valves are too tight, they can do that, and eventually they will burn a valve and damage the engine. So valves are one of the most neglected things on a Honda engine. They don't get adjusted when they should be adjusted, and they're not that difficult to do. But if they don't get adjusted, if they were to get too tight and keep the valve hanging open, it'll burn that valve and damage the engine. Did that light coming on happen after the starter was replaced?
