Product Description
Triumph Stag Reconditioned Carburettors
Stromberg CD175 Carburettors
Overhaul & IDentification
IMPORTANT
All parts listings and illustrations here refer to UK & European models only
It is quite straightforward (with the help of a workshop manual) to
service or overhaul your own carburettors. It is an important task as
fuel economy and performance can suffer due to lack of maintenance.
Incorrectly adjusted or worn carburettors can also lead to premature
engine wear because unburnt fuel that remains in the the cylinders
causes 'bore wash', which eventually glazes the bores, resulting in
excessive oil consumption.
We supply reconditioned carbs, in pairs and strictly on an exchange
basis. The chart here however, is primarilly for identification
purposes. We actually class our units as MK1 or MK2 in order to simplify
and maintain a continuous supply of exchange carburettors. If your Stag
is one of the
very few that was equiped with ' tamper proof carbs', please contact us.

NOTE: During the life-span of the Stag, Triumph/BL made numerous
specification changes to the carb's and components, they also changed
and/or superseded original Triumph/BL carburettor part numbers (e.g.
311968 to RKC823) whilst still using the same Zenith ID number. Many of
these changes are not fully documented, however, to the best of our
knowledge, the information above is correct.
USA EMISSION MODELS
Stags for the North American market had to comply with very strict Federal exhause emission regulations, accordingly, the carburettors and the engine breather system were unique to these models.
Carburettors & Service Parts
Although the majority of the service parts appear to be the same (IE,
needle valves, diaphragms, service kits etc.), the carburettor bodies
are not due to the installation of a by-pass valve.
However, all is not lost!
Every Stromberg carburettor has a unique 4 digit specification number
(IE: 3289) stamped either on a brass/aluminium tag or on the actual
carb' body. Once we have identified the cuarburettor number, and we
know your full vehicle details (model, year, engine, & chassis
number) we should be able to supply the parts that you need.
Engine Breather (Emission) Systems
Because we have access to factory parts records/listings/stocks, we may
be able to supply some breather emission parts, please enquire.
