997 cooper carbs

[S33blo]

Hi all,

I’ve had these what I believe are 997 cooper twin HS2 carbs and am looking to confirm what they’re and an idea of value.

Manifold number is 12A-309 P
Carbs tags are AUD 15L / AUD 15R
Air filter are PD2334/18 and PD2334/19

Thanks

I don't know about the values etc but I'd suggest that the things of value are the original filters and the tags - if they are from a 997. The rest of the set-up is just generic SU.

Stand to be corrected of course

You’re probably right, would be a shame to spilt them up as they’re so original. AUD15L + R are listed as 1961 - 1962 only so not sure if they’re different from the later ones

Can't be 100 per cent sure from the pics, but I think those are the earlier (wider) heat shields too. Square receiver for the springs as the airbox cut out wasn't required yet?

Nice complete set of 997 carbs, with tags , early filters and heat shields. As to value unusual to be so complete.

They’re slightly wider, I didn’t realise this was a thing. Interesting

The person I purchased them off said they were taken off early in the cars life along with the head. Unfortunately the head was binned the week before

I wouldn’t say that the carbs are just generic SU. If you want a genuine period set of Cooper carbs they look like a good option

The fuel bowl lids look like the right ones for that age
The fuel bowls look like the early type with a fixed angle
The RH carb has the vacuum advance port and the LH carb doesn’t which is correct for Cooper. The vacuum advance pipe is also there
The linkage has the correct pin type and not the new folded metal
The carb bodies are the early type with no breather ports

That set looks like it's 100% bang on the money for a 997 set. The carb bodies on the early HS2 carbs are different to the later ones, as are the float bowls, as are the lids on the bowls.
As already mentioned, the heat shield is the correct early type although it has been modified on the clutch side. this was quite common as you would have better access to the slave. This would be a set of ones made towards the end of production. The early sets had the float chamber tags anodised blue

The bowl and body type is interesting. Those fixed bowls are I thought 20Deg types. The 30Deg setup use the special rubbers.

These bowls also have the rubber grommet to set the at 30 degrees. The earlier type used on the 850 had the sat without the rubber

Would be interested in seeing a 61 built 998

Thanks for all the information, these have gone to a 997 restoration
