Hmmm, after further review of my SU Speedsport manual your SUs do not
exist. :) At least up to 1975. Sounds like quite a mish mash of unlike
carbs to me. It will be interesting to see what others come up with on
where these carbs came from.

> The car was converted to a triple SU set-up (I was told by the shop they
are 2" and have assumed they are the HD8's used for Healey BJ8's).
>
> The carbies have been overhauled by a reputable local shop but they were
unable to adjust them to idle correctly. The carbies only have one adjusting
screw & the shop has adjusted them to the max but the highest idle speed
possible was 300RPM at which they constantly stall.

ideal.

> When looking at the carbies, they do not match the illustrations in my SU
manual for either HS or HD type carbies. Neither can I find the carbie
serial numbers there or on the internet. The carbies lack (by design):
> - Fast idle adjusting screw
> - Throttle adjusting screw
> - Jet adjusting scew
> Instead, they only have a screw in the location marked in the book as a
"Slow running" volume screw. I was told by someone else that these may have
been later emissions compliant SU's.

> Can you please help me identify these carbies. The numbers on the units
are:

> - Front: carby body - 709c; bowl tag - AUD 157c; junction with manifold -
C 13 6.
> - Middle: carby body - 709c; bowl tag - AUD 157f; junction with manifold -
C 13
> - Rear: carby body - 2044 (IGN); bowl tag - AUD 157c; junction with
manifold - C 9 6.
