General Notice

SU has been making carburetors (or "Carburetters" as they call them themselves) since 1904 and the number of different models runs in the hundreds.
In order to find the correct part for your specific carburetor, it helps us if you have the so-called "tag number" at hand.
This tag number is usually stamped onto a small aluminum tag found under one of the screws of the float chamber cover like in this photo:

Without this tag number, the search for the correct part is, also for us, rather challenging as most SU carburetors are look-a-likes of each-other and going just by vehicle type still leaves many options open.

So, feel free to contact us by email if the set or parts that you are looking for is not yet listed but please have this tag number at hand.
