You can run Webers without chokes. What you need to consider is that with modern cams, plus cylinder heads and so on, there is more than enough metering signal strength to accurately meter fuel with the auxilary venturi alone.

I've run 47mm chokes in 48mm carbs on a road course / street car running a 408 cid engine (in a customers car) to good advantage.

I didn't remove the choke, but I am certain it would have benefited from the increase in area.
