SU H-Thermo Carburetor Parts.
On this page you will find our currently available genuine SU Carburetter Spare Parts for the SU H-series THERMO carburetors.
Please note that this page is specifically dedicated to the so the so-called THERMO version of the H-series.
These carburetors are equipped with a THERMOstatic choke and consequently are significantly different from their regular H-series brethren.
Important parts like, for example, jets, are not interchangeable between the regular H-series and the Thermo versions.
Therefore, please consult this page if you have a Thermo carburetor, regardless of it diameter (H4-Thermo, H6-Thermo etc).
Please click HERE for the exploded view drawing of the S.U. H-Th carburetors.
The numbers in the drawing correspond with the numbers in brackets in the item description on this page.

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.
