yes - i bang on a bit about Italian Webers and Dels over other stuff
here are a couple of pictures that I think prove a point
One is a picture of the washers that sit under the needle and seat of some Chinese IDF's and the other picture are venturis
L to R is Chinese, Spanish and Italian
Yes the Italian ones are larger than the other.
but seeing carbs are all about smooth air flow............
Just sayin' ....................... 😎
