I own a TR3B that has a pair of SU carbs with the ID numbers of AUD 505. This website:
https://sucarb.co.uk/cf/vehicle/list/?manufacturer=MG&vehicle=M.G.B
say this is an HS6 for a special tuning MGB for a 1798 engine used from 1969 onward. However, when I go to the Moss catalog under MGBs they only list an HS-4 carb. Does anyone know anything about these carbs and where to obtain parts? I need new needles but need the part the parts number.
Any help will be appreciated,
Mike
