I had a worn pair of 150CDSE on my Mk3 GT6. Couldn't lean them off enough.
I got a NOS pair of 150CDSEV (US spec with extra emission control) from the carburettor hospital and a refurb kit.
Carefully cleaned them and fitted all new seals and diaphragms - an evenings work and quite fun.
Sourced a 'bifurcated' flexible Late GT6/TR6 choke cable from the US.
- Had a RR session to set ignition timing curve (I have a 123 Tune ignition)
Runs very well now.
