Carburetter Assemblies |
The twin HS2 (1 1/4" diameter) carburetter installation was fitted to Cooper and Cooper S models between 1961 and 1971. Identification of your HS2 carburetters is absolutely necessary before ordering parts. It should be a simple matter of looking at the aluminium tag attached to one of the float chamber lid screws; the number stamped on the tag (followed by 'L' or 'R' for left hand or right hand carburetter) 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. Reconditioned and in some instances new carburetters are available; please contact us for details. |
|
|
|
|
|
The carburetters listed here are all of the fixed metering needle type; 'swing' or biased needle type carburetters were introduced to other Minis after the end of Cooper and Cooper S production. |
|
|
|
|
|
A replacement twin HS2 installation is also available, faithfully original in appearance. The installation includes a pair of HS2 carburetters together with interconnecting linkages and fuel lines, manifold and heatshield assembly. |
