40 mm Zenith Settings Wanted

I've been communicating off-line with another BBS user on some weber carb settings. This prompted me to check my library for data about what works and what doesn't. I found some data for 40 mm Webers (Upfixen V3, V11 and BA's bible as well as a couple of recent posts) which resulted in about 8 data points. It would be great to fill in the data further for Zeniths.

So what sort of carb settings are people running? Please give engine size, summary of the level of tune or cam spec, the Venturi, Mains Jets, Air Correction, Emulsion tube and the idle jets.

Bump

Ok Guys. Here're your chance to show how you've got the "perfect" set-up for massive 911 HP without spending a lot of money on Webers. Come on - brag a little!

Collectively this group probably has set-up more carbs then most local mechanics. If you're like me, I often have lots of information on a subject, but I just forget it when I need it or just can't lay my hands on it. Putting it all in one place (here on the BBS) will make is easier for all of us to troubleshoot tuning issues and set-up our carbs correctly the first time.
