Triumph 2000/2500/2.5Pi Carburettor Components - SU Carbs - UK Specification
Overhaul & Identification
It is quite straightforward (with the help of a workshop manual) to service and overhaul your own carburetors using the service items listed in this section.
Both fuel economy and performance can suffer through lack of carburetor maintenance and with the recent tightening of the MOT regulations regarding ‘Exhaust Emission’, it is important that they are properly maintained in good working order.
Incorrectly adjusted or worn carb’s (as well as poorly maintained ignition systems) can also cause premature engine wear, because unburned fuel that remains in the cylinders causes ‘bore-wash’; which eventually glazes the bores, resulting in excessive oil consumption.
The carburettor listings here are primarily for identification purposes, they will also show if you have the correct carb(s) fitted, part numbers/engine numbers are quoted to help identify original factory specification, and relate to carb’s fitted when the vehicle was new and not subsequent replacement.
To check, the carb(s) can be positively identified by a silver tag which is usually located on the float chamber and is marked with the part number, IE: AUD604F.
Having identified your carb(s), all you need do is then refer to the corresponding carburetor components/kits.
