Identifying a Solex 32 SEIA? Or EISA?????

[Piet]

I've got this carby and manifold off an 845 ventoux engine, either a Mk1 R5 or possibly a 1970s/early 80s R1123 R4 variant???
No ID tag, only some numbers stamped in the side. Is it an EISA, an SEIA, and what variant?

Any good explanation would be greatly appreciated. Next stage, decide whether to rebuild and try on my car. The bigger choke and accelerator pump should be helpful I think, providing its not worn out. The anti-fume valve and associated gubbins might not bode well though...



I see Franszose, Melun etc are selling a very similar looking chinese one, has anyone had any good results trying them?

So- no answers but perhaps if I throw up a couple of suppositions someone can correct me...
I think it is an SEIA. The EISA looks broadly similar but has the accelerator pump on the opposite side. The other difference, I think is that one has the external defumer valve (as this one does) but the other (presumably the EISA) doesn't. Here's another pic, I should have put it in the first time.

Aliexpress offer a chinese Sherryberg carb that looks identical to my one. Melun offers a carb (now OOS) for the 4L that resembles what I am calling the EISA.

Does that seem right?- next question, Can someone confirm this carb was fitted on 845cc R4s or at least 845cc mk1 R5s? I have found conflicting info.
And finally, what the jet sizes should be for that fitment?
Any help would be useful!

 

[Piet]

Oh, and also rebuild kits seem applicable to both. Is that a correct assumption?

I don't know if this is any use - it's from the R5 RTA.

Thanks Andy- that is a help, much appreciated!

My General advice-Stay Away from Chinese copies-they may look as a leg.carb sitting on the shelf-so That's where they need to sit (as a dust-collector-Only)

Indeed, as @reidalpine wrote, never use cheap ching chong pong junk, just like everything else from the world's most polluting country and doing nothing about it as more countries do because they don't care and greed still rules the world.
