Hi Scott,
Looks like they may have been from a Jaguar. Check here:
http://www.burlen.co.uk/burlen-user/default.asp?Category=burlen&Service=Carb
Spec&Veh=246. The weird thing to me is the "c" in AUD 157c stands for center
and "f" stand for front. Burlen lists these carbs as HD8TH.

Best,
Greg

Hi listers - need some help on my Healey BJ7 carbies.

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.

I have used my pedal stop to bring the idle up - but this is far from 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.

Thanks
