I love the Internet and am amazed as to how much great information is out there and readily available. I have attached to this post, some information focusing on the "flow" of Weber IDF (40mm, 44mm and 48mm) carby's that I found on the Net.
I thought that it would be a good idea to provide a list of the various parts contained in a VW transmission. This should help when ordering parts but more importantly, to better understand the terminology.
