Quoting datzenmike here,
Loosen the nut and turn the screw in or out lock the nut again. Intake and exhaust at both set at 0.012". Just slip a feeler gauge between cam lobe and the adjuster.

ex. and in. on #1
int. on #2
ex. on #3
Turn motor ONE revolution and set
ex. on #2
int. on #3
int. and ex. on #4..... done.
You would actually measure between adjuster and top side of the valve correct?
