Because firing the plug earlier would allow more burn time and bring the WBO2 back to where it should be.
Or am I thinking about this wrong?
Not exactly if your WB reads rich then you need to change your MTF IF you have the base fuel tables set to what you want the targed to be

Set your base fuel tables to what lambda target you want then change the MTF to get the AF to match what AF/lambda you want

Timing will do little to change the AF
