Original B20B SU carburettor set
This is a set of SU parts from a 1968 B20B 145S. I think there's very little missing plus some few spares because my engine was tuned and I recalibrated them, so original calibration + extras, with one spring required. The bodies are good as in my experience the pistons dont wear badly because they are clearance fit to the bell housings. An SU refresh kit of gaskets and jets would be advised. There's several jets but the link-tube stiffens with age. The jet tends to wear more than the needle because the needle is spring-loaded against one point of the jet. It looks like one new spring is required: adding sections of extra cut spring is an SU calibration technique that I used.
