I am sure there is more than one way to fix the "early" fuel draw which can lead to puddling problems. I am sure the new owners of BME have talked extensively with Keith and are going forward with the best option available.

As Altavillan mentioned, my 3 needle carb sure runs sweet.
He might not know it yet, but when I start flying my new plane he is going to take my 3 needle carb and reproduce it a couple of times

Amp-Go richer on the bottom then start leaning the high until that mid range richness dissipates. You can some what crutch the high with the low. The richening mid range is NOT from the low, it is fuel being drawn from the high too soon. That is why when you lean the high to correct mid range you go lean on the top with the un-modified WB25.
You can richen the low "tremendously" without affecting the mid range. Just try it and see if it helps.
