Special Tuning Carburetters
We could not hope to cover all the SU carburetter specifications, both official and unofficial, that Minis have been fitted with over the years. What we can do though is to acknowledge the factory's own Special Tuning range, which we show here. Space precludes us from listing all the parts for these carburetters, so we have limited ourselves to showing complete carburetter assemblies, linkages, gasket kits, service kits, rebuild kits, sundries kits and a range of more frequently asked for parts. Most other parts are however available on request.
         
Identification of your carburetters is absolutely necessary before ordering parts. It should be a simple matter of looking at the aluminium tag attached to each float chamber lid; the number stamped on the tag should correspond to one of the carburetter part numbers listed here. Failing that, if the tag is missing, a study of the applications below will help.
         
H4 Carburetter Assemblies
One of Special Tuning's most popular products of the 1960s, the twin H4 (1 1/2") carburetter installation came in four different specifications: right hand drive or left hand drive with choke mechanism and right hand drive or left hand drive with thermo jet (without choke mechanism). The new replacement carburetter assemblies listed here are fitted with AUD1118 CP4 needles (AUD178 carburetters) or AUD1265 MME needles (AUD59 carburetters). Reconditionedcarburetters are available; please contact us for details.
         
The replacement twin H4 installations are faithfully original in appearance. They are supplied with inlet manifold and linkage, or as simply a pair of carburetters (with choke mechanism) or a pair of carburetters with linkage (thermo jet).

HS4 and HS6 Carburetter Assemblies
In the 1970s, Special Tuning offered a choice of twin HS4 (1 1/2") or twin HS6 (1 3/4") carburetters for use on 998cc and 1275cc Minis (HS6s were available for 1275cc only). Earlier carburetters were of the fixed needle type and later versions had 'swing' or biased needles. The new replacement HS4 carburetter assemblies listed here are of the biased needle type. No Special Tuning HS4 or HS6 carburetters were manufactured with Capstat temperature compensating jets. Reconditioned carburetters are available; please contact us for details.
