Weber Carburetor Designations

It is not easy to organize Webers into neat families for two reasons. In the first place, Weber did not set out to construct a tight little family of carbs. He was interested in building carbs that best matched the current need. As a result, there was never an overall scheme of things. Secondly, he named carbs in his native Italian. So if you are unfamiliar with words like doppio corpo or orizzontale, weber terminology can be confusing. To further muddle the issue, Weber typically created different model numbers whenever he could. He would give carbs unique names even though they differed only in jetting or some similarly indistinguishable feature. Thus, a DCN fitted to a Lamborghini was a DCNL. If fitted to a Ferrari, the same carb became a DCNF! Another twist is represented by the IDA carb. It may have either two or three throats, yet the same identification letter. While it would be helpful to have a neat chart of Weber terms, its simply impossible. Nevertheless, as chaotic as the terms are, there are some common threads in how Weber named his models.
