What is the engine make and model? That info should be right above the engine serial number.

Edit: For a small motor like this, which produces little heat, appropriate clearances would be:
INTAKE
.03mm, or .0012in
EXHAUST
.05mm, or .0020in
If they sound a little clacky, you could adjust them slightly tighter, but these will do. Exhaust valves always see more heat, so they are generally set up looser to allow for valve stem expansion.
