Without removing the magneto cover, insert a 17mm socket into the valve position, shine a light inside, and you'll see a marked line. Adjust the valve clearance by aligning with this line. Remove the valve cover, then take off the cylinder head to reveal two screws. First, wiggle them slightly to feel the gap, then adjust to make it a bit smaller.
