At a quick glance with all the parts mounted in the engine, the trigger unit on a 2K3 looks to be attached to the engine case, but it's not.

Correct. If you turn the stator Clockwise you will advance your timing. If you turn it counter clockwise you will retard your timing.
Timing is a funny thing. You want the most amount of timing you can get at a lower RPM with out detonation for a strong bottom end and then retard for High Rpm's for good top end. Our Pro stock 1000cc Arctic cat drag snowmobile running on 114 octane race fuel turning 9300 Rpm's has 32* BTDC of timing at 3000 Rpm's but only 13* BTDC of timing at 9300 Rpm's. We have advanced the engine to 40* BTDC at low RPM but the engine started and ran backwards.
My Old Yamaha IT200 had no timing curve at all. It started and stayed at 20* BTDC. That worked great for low Rpm's but left a lot on the table for top end.
