Charles – no, the gold ring is the support plate and it is fixed in position (it doesn’t move); the magneto sits on top of the support plate.  The magneto plate fastens to the silver colored retainer ring which sits below the support plate.  You can see 2 screw holes in the retainer ring and there are 2 more screw holes on the back side of the ring (hidden from view in my picture).   There are 4 screws that go through the magneto plate and fasten into the retainer ring.  The retainer ring rotates with the mag plate as you move the throttle.

As fleetwin notes, be sure the motor is fully engaged in forward gear so the mag plate can advance fully to the stop.

You have the correct understanding on adjustment of the economizer linkage – carburetor and throttle advance correctly synced, then mag plate advanced to wide open against the stop, then adjust the stop collar on the linkage rod.
