Second episode (of six!) of the "True or False" series of articles dedicated to tank carburettors for karts (did you get the first one? Here it is: “True or False | Float Bowl Carburetors in Karting: Big Truths (and Persistent Myths!) About Jetting, Maintenance, and Tuning – Part 1 of 6”). Giuseppe Riva, technician of the Research and Development laboratories of DELLORTO (a leading Italian company in the production of carburettors for karts and motorsport), one of the leading experts in the field, answers our questions. The 6 questions in this episode concern: the atomizer and its role in the formation of the mix between air and fuel; the angle limits for the installation of the carburetor; The reliability of the needle valve... And much more!
