G'day Mystyler,
Here's a pic of how to position the screwdrivers. This is an external coil 160, which still has contact points under-flywheel, but the same technique applies to the coil-under-flywheel models.
I haven't removed the nut for the pic, but you'll see the ratchet drive in the background, with a 13/16" AF spark plug socket on it.

The vital bit of this method is, the flywheel is raised by lifting the handles of
both screwdrivers
upward simultaneously.
If it doesn't move straight off, you can apply a 'rocking' motion by alternating the upwards pressure - that usually shifts them.
This technique isn't mentioned in any of the workshop manuals, but it sure works a treat!
