The round wire, in cross-section, is a surprisingly dirty (non aero) obstruction, and also disturbs air around it. It's the reason screens do not protect jet engines against bird strikes: ruins the mileage.

Scoop with a pair of K&N filters.No difference in AFR with or without filters. Without filters there is fuel being sucked out causing fuel vapor towards the windshield at speed.
HEMI-ITIS has no cure. My condition is fully BLOWN!!

I run screens on my carbs for the street and put my Super Shaker over them. At cruise nights I cap them with the Moroso carb caps. Don't trust anyone dropping something down the carbs, just in case.

If a screen is large enough it's harmless, but per square inch it's a restriction compared to fully open. The round wire used is a very dirty aerodynamic shape compared to a teardrop, ellipse, etc.
