First make sure that the grip plate is secured into the grip (a loose grip plate makes a mess of setscrew adjustments).

Drive in the motor set screw all the way in until you feel it bearing the motor up against the bevel gear (screw gets tight). DO NOT FIRE in this condition. Back the screw off about 1.5 turns and thump the handgrip to get the motor to push back and set against the screw.

Fire in semi auto mode while backing the screw out in quarter turns. Listen to the sound of the engagement and stop adjusting as soon as it sounds less grindy. Go too far and the teeth will not engage enough and they'll strip.

When you're at the sweet spot, remove the allen key and reinsert it so it's pointing straight forward relative to the barrel (or close to it). Back the screw out 5 turns (IMPORTANT TO COUNT ACCURATELY) and apply a small dab of blue (temporary) loctite to the exposed screw threads. Spin the screw back in 5 turns to wipe the loctite into the grip plate thread and secure the set screw. You might have to spin the screw out more than 5 turns to expose any threads. Just don't go far enough to remove the screw, and keep track of how many turns you've pulled out.

Ideally you should measure motor current while backing the grip screw out. Evaluating tooth engagement with sound is pretty subjective and not particularly repeatable. I'm contemplating a circuit which can filter out the noise of an AEG motor so you can measure current with a low cost multimeter (not very noise tolerant) and properly adjust a grip screw. Not exactly huge appeal, but it's definitely in line with my company's namesake.
