Spent ages on the phone to the UK's main supplier of Weber replacement carbs today, only to be told that what I think I have isn't possible. (I reckon I have a MkI Scirocco lump in the Golf, but the MkI Scirocco has a longitudinal engine, rather than transverse)
So, I've taken some snaps, and put them online - hopefully someone can identify it for me:

I reckon I have a Zenith 2B2 or 2B5 carb...... however, I'm told it's more likely to be a 2E2..... but it's stamped 2B......
You really need to ascertain *exactly* what lump you have, by sounds of it.
However, the Scirocco and Mk1 Golf IIRC, shared lumps, and I've always been led to believe that the Mk1 Scirocco was heavily based on the Mk1 Golf, so I doubt that the engine would have been mounted round the other way.
You really need to speak to a VW specialist methinks... one that's been around long enough to know the score with regards to the similarities between the two cars, and which will be able to decipher the chassis / engine numbers in order to ascertain exactly what it is you have.
The other possibility of course, is that your engine should have the 2E2, but that the 2B series fitted without modification, or with a manifold change at the same time.
'Webcon' got it wrong with the Scirocco engine orientation. Argh!
Anyway, it's an FR engine, 1588cc. Zenith 2B2/5 carb.
Not listed for my year of Golf in the Weber book - but there is a Weber replacement for a 1588cc Golf Auto, on a different year, so I'll order one of those.
Thanks to anyone who chipped in with some info, it motivated me to find that engine number.
Hmmmm - if you solder up the full power enrichment device and rejet them properly they work after a fashion on smaller engines than the 3 litre they were designed for but it's somewhat of a lottery. I'm not a devotee to be honest.

I'm not at all sure why women like men. We're argumentative, childish, unsociable and extremely unappealing naked. I'm quite grateful they do though.
I've seen one fitted to a 1.3 Skoda rapid that was lightened, and balanced, with a 4-2-1 manifold, group B spec system, and a big valve ported head. Went like stink. Was a most fantastic autgrasser.
It won the season in his local league, but was then disqualified. He had blown up the original ropy engine, and had sourced a 135 lump instead of the 136 that was originally in it. And there was officially no 135 Rapid that year in the UK.
Difference between a 135 and a 136. The 135 had lower compression, but mechanically identical, same block, same crank, carb only difference was the head which he had modified anyway. By the time he had had the head skimmed, and the rest done he was actually running far higher compression than the 136 anyway. His engine was within the permitted specs for the class he drove in, but his fellow competitiors just wanted a nice loop hole to hang him from.
The jettings seldom far enough out to make much real difference because any amount of air that gets sucked through regardless of throttle plate position, or rpm it still needs to be "correct" mixture. A carbs just a scent sprayer! Suck harder and you get both more fuel and more air = correct still. And the opposite is true.
You CAN improve the settings with a little rejetting, fuel level adjustment, idle mixture setting, but you can do that on ANY car!
