There is probably enough information in Haynes relating to the Weber 30/32 DMTR 90/250
I guess this is the one you mean.
There's enough to set up idle speed, idle mixture, float adjustment, valve plate openings, fast idle, and the anti-flooding device....
It should be in the link posted for you back in February..
