Reply to "Happy Day. New Weber’s arrived!!"

First off, I'm only familiar with Dellorto carbs, but I have read a lot about Webers and they are pretty similar in operation/jetting, so here's what I'm running on my 40mm Dells, set up by Dave Hogland when he was still at Blackline Racing:

The jet sizes are:

.45 idles

1.30 mains

160 air correctors (to slow down the fuel through the main jets to overcome the hesitation)  I might start with a 180 before hopping to the 160.

.35 Accelerator pump jets

32mm Venturis  

So my idles match yours, my Mains are slightly richer but the big difference might be the air correctors (200 AC is pretty big, in my book) and the Venturii size where mine is a 32.  I used to run a 34 main venturii and it had a bit of transition hesitation that is now gone.

That's all I've got.  Mine run great at around 14.1 most of the time, leaning out a bit on transition and then recovering but you can't feel anything (and that's what counts).
