Twin carb option ???
When lookiong through the AMAL Carb settings list, for 1957 Model 30 I see carb type 376/78. However there is also a line that shows carbs for the 600 twin "(In Pairs)" with 376/95 or 376/96. I havn't seen paired carbs on a mdel 30, is that really an option. If so, what inlet manifold is used?

I had trouble keeping the fasteners up tight on the bits I had, and reverted to a single carb after a bit, with no obvious difference in performance for normal purposes. But they were a talking point!

Re: Twin carb option ???
here is a picture of what I believe is the original manifold.

Re: Twin carb option ???
the picture with the 2 manifolds is for a 650cc not a 600cc

Re: Twin carb option ???
Interesting thread this (to me), however rarefied the issue might be.
Both the original (never seen that part before Poul, thanks!) and the 650 ones seem to imply a parallel fitment, which depending on space might require a bottom-fed chopped right hand carb? Maybe /95 and /96 376s are . . .? The ones here are off my 650SS (different serial numbers) but the only Monobloc option on those heads as 'handed' ones clash in the middle.
I can't recall seeing any AMC twin with 2 carbs, other than my lashed-up 500, where they sat atop absurdly over-bored (to 70mm) G9 cylinders running equally absurdly high compression (all long-abandoned) - but I probably haven't looked closely enough.

Re: Twin carb option ???
I machined up some two part manifolds and fitted twin concentrics to my G12.
Close fit, but they went on parallel.
That was in 2018, out of curiosity I just looked up the receipt for the carbs... £230 inc. vat the pair from Burlen.

Re: Twin carb option ???
My G11CS is fitted with twin carburettors, first I used the orignal manifolds, but it was difficult to get them air tight, so I mad my own manifolds version 2
, but it was not easy to fit carbuterttors, so next winter I made version 3, they looks like the originals, but I made some internal modifications, and now they are doing the the job wery well.

I have a 650 with a special manifold,
