[Roadsters] Datsun 2000 SU needle charts

[Keith0alan at aol.com]

Hello all,

Do a Google on "Haystack SU Carb Needles". It is an old program for
selecting needles. It also contains a database of all of the British SU
needles.
I took the data and imported it into Excel to sort through it.

    My graph uses the stock N-17 needle as a baseline.  The distance above
the baseline is how much richer the needles are than stock.  The numbers
across the bottom are the station number. Starting at the base is  station 1
and stations are 1/8" apart.

While Bruce is off for Thanksgiving, I wanted to get a head  start on needle
choices from Datsun.  Do any of the Roadster folk know  of a place with the
various needles measured out?  Google turned up  the Keith Williams write up
and his comparison of needles, but I can't  really make sense of his graph
and would like to just get the raw numbers  (or his graph  explained).


Thanks,

Julian
