How do you remove valves on a 5hp Briggs?

Take the head off the engine then you will see the top of the valves. Look on the side of the motor right below the valves you will see a cover with two screws remove them and you will see behind it the stems of the valves - there are two springs you have to push one at a time and there is a slide clip which slides and pops off. Then push the valves up and pull it out of the engine.
