The dribble was caused by a loose AV. It needs to be a tight fit to the carb body.
Just lightly digging on this topic, but on a different issue in item 1.
1. BMW Mine did the same thing in terms of leaking, it was a combination of fuel pressure and not having a phenolic plate under the carb, so the fuel began to boil.
2. I do not own a Weber currently, but if I understand this post, he suggests after 4 years of usage, that Weber attempted a modification, What is the function of this spring (AV related?)
as for the auxiliary venturi's, that is exactly what I was looking at today. Mine also have a bit of play, on both barrels. I do however have them of a bit later type that have a spring on the stud opposite of the main fuel outlet. This probably is meant to keep the fuel outlet connection sealed. I was able to tap a 0.2mm feeler gauge in the gap between the stud and carb. Maybe this vibrates while driving, but the spring is quite strong. It is possible to pull them out without much effort.
