MGB MGB Special Tuning 4 Cyl Carbs - Need Help w ID and Replacement Needles

All:

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

The Special Tuning stuff for MGB's was a set of increasing performance enhancements, in stages. Those HS-6 units weren't normally fitted to an MGB.

I will suggest getting in touch with Joe Curto, he would be the go-to for the needles in any event.
