Hi All
can anyone confirm the correct twin su hs2 carbs and numbers for my mk 3 cooper s built dec 70

did the carbs have the vacum advance blanked off as mk 3 didnt have vacum advance ??
does any one know correct numbers for float chamber tags should it be -
aud 440 L +R ??
also did mk 3 s carbs have the 45 degree angle brass outlets that angle towards the centre of the carbs , when mounted on manifold,
sorry but i do not know what these brass tubes are for fuel vapour ??
one more thing does anyone have a set thay want to sell ???

any help much appreciated

The manifold should be a stamped 12G2463(AEG573 ground off) large flange one with a one way valve fitted for the servo take off (small hole)
The big hole(center) is blanked off.

I have a very nice set from a 1300GT which may be very similar ?? available for £150 if any use. Will check and advise numbers if interested.

1300GT carb's AUD 431 will be similar (other springs and needle) the manifold is different.

Other sets on 1300GT(from '72 on); AUD454 and 496
