I'd go for the new carb...If 'originality' really bothers you it's a case of saving up and getting the right one later (or putting it on your Christmas list..:smile: )
Personally, I don't bother with second hand (or reconditioned) carbs unless I have to, I've found in the past they just create more problems. Most second hand carbs are second hand for a good reason...Usually excessive wear of the body and slide (at least).
Reluctantly I've just had a 1000 Series Concentric reconditioned for my Gold Star but I'd much rather have bought a new one. Sadly they aren't currently available...Ian
In the world of Pre65 trials the Wassell carbs don't have a good reputation.Rapid wear of the body and slide make it difficult to maintain accurate mixture control at low revs.(Just like the old original Concentrics)We always use the Amal premier units with a hard anodised slide. Even they can benefit from a couple of tweaks when new,but once set up correctly they last well.
I'd save up and buy the correct Amal unit,it will always be right then and the "experts" won't be always telling you its not original.
As an aside on new concentrics it is important that the flange nuts are only just "nipped" up as any more force distorts the body and the slide will stick. A few times at Pre 65 scrambles and Red Marley we have sorted bikes by just loosening the flange nuts half a turn!
