Secondary main well air bleed tubes

I may need to revisit this.  I had the four (4) .024" holes in the tube (and maybe a little too high) and it seemed like it was doing wierd things to the fuel curve.

0.027" is pretty small for the well re-fill holes (even in many stock model carbs I've seen).  I would guess that the POE fuel probably isn't much of a player after intial WOT?

The way I heard that explained was that it's fuel is fed by gravity once the fuel level drops below the re fill holes. So it's pretty much a constant flow rate after that ( limited by the 2 orifices). And with increasing air with increasing rpm and no correlating increase in fuel flow, it's contribution gets leaner at higher rpm. So yeah when first at WOT and lower rpms, it's not much of a player after that

  Now I just catch glimpses of the meter while trying to keep the car on the road.  LOL

 That's the same problem I've got, but I'm trying to push the record button on my little voice recorder to make notes with, while looking at the AFR gage and staying between the ditches and not bouncing off the guardrails.

I think I was just doing some testing here looks to be about 9 years ago. The AFR & RPM numbers aren't right in the sidebar.
