I have discovered that in my big pile of things I have acquired over the years I have a Weber 40 DFI5, reputed to have been used on the Group 1 touring cars in the UK. Has anyone got any experiences with this particular carb and is it any good on the street or is it an outright performance carb for racing, cheers JR

OK the Weber 40 DFI5 is on the market, $350 if anyone is interested, this is a factory manual choke direct replacement for the 40 / 38 DGAS / DFAV
