It's interesting that it's running rich after the rebuild and not
before.  If your valves were messed up before, maybe your O2 sensor is
fried.  Try disconnecting it.

If not, there is an air/fuel adjustment mixture on the AFM, hex key
adjustment.  You may need to take off the cover for the screw.

The last resort is to take off the cover of the AFM itself and adjust
the spring tension by adjusting the wheel.

Disconnecting the O2 sensor is painless.  Messing is with the air/fuel
screw on the AFM is fairly safe if you count the number of turns
accurately and write it down.

Messing with the wheel can have bad consequences.  If you adjust the
wheel, get some whiteout marker or nail polish and mark the wheel
position prior to adjustment.  Then, only move it a single click at a
time.

Probably better to find out why it's running rich.  Bad O2 sensors
cause this frequently.
