Herald HS1 manifold and later carbs

[Paudman]

Hi y’all - anyone know off-hand if the twin-carb manifold on early Heralds, using H1 carbs, will take later HS2 carbs as a straight fit? I’ve been asked by an owner who can get new HS2 carbs much cheaper than having early H1 carbs refurbished, but I don’t have any close to me to check for fit. (Don’t work about the bigger size or other required mods; that can be handled if they fit the manifold.)

I guess he wasn't happy with the answer I gave him...

He needs the HS2 manifold as the carburettors have a different footprint, 1 & 1/8" throat versus 1 & 1/4".

Cheers,
Bill.

Lol…. happens all the time…. maybe I should tell him something different?

Well, yes, but in the first post of this thread it says:

I'm guessing "work" was a typo for "worry", so he's saying he knows they're a different size throat, the question is whether they're also different shapes, mounting lug locations, etc. If he wasn't sure about that from your answer, then he might well be asking for clarification.

My answer was a lot more comprehensive than what I've posted here...

Yes it was, sorry but that damned spell checker is going to be forcibly removed one of these days. I’m taking it from the e-mail that I received that the fit onto the manifold is the only problem, all else can be resolved with a bit of adaptation or modification if required.
