Not bashing anyone so no clue on that but you know who I bought your carb from is a blow hard and even stood you up so your call to take it that way but the design is flawed imo for a street car especially like an on and off switch. Just like the QF SV-1's. If I loved the carb I'd still be running it and a Dommy will kill those again imo and MANY others across the board........
