He's right, a standard manila parts tag works well also.
.012-.016 is the measurement but the tag or a card works good because it conforms to the shape of the flywheel.
Insert it between the mag and the flywheel, loosen the magneto mounting screws. If the flywheel is turned so the magnets are there, they will pinch the tag and just tighten the screws.

There is a special guage for this, but I've been using a standard business card for years without problems.
