How to adjust the valve clearance of the SFH C9 engine?

No need to remove the magneto cover. Insert a 17mm socket into the valve position, shine a light inside, and you will see a marking line. Adjust the valve clearance by aligning with this line. Remove the valve cover, then remove the cylinder head. You will see two screws. First, shake them slightly to feel the clearance, then adjust it to be slightly smaller.
