The guys in Nissan Datsun Sports Owners Club (NDSOC) who were considered to be the experts when I first joined in 1990 told me not to waste my time trying to tune the later carbs. If your engine is modified over standard, there is more tunability with the earlier carbies! If you get hold of David Vizards book on tuning Mini engines, he devotes a couple of chapters to tuning SUs ie modifications that include things like thinning the spindles, modifying the slides and increasing the flow rate of the carby quite substantially. I don't think the later Hitachi SU lends itself to any of this, but others may disagree? Steve, what do you think?
