I'm guessing that richening up the main circuit helps cover something that may be lacking in the transition or accelerator pump circuits. Depends on the RPM where you're seeing the issue. Below 2300 I'd expect a combo of transition slot and accel pump, with accel pump predominating. Above 3000 I'd expect a combination of main circuit and accel pump, with main circuit predominating.
But yea, the WBO2 and vacuum gauge reveals all.
