There is a bloke that attends alot of the shows who reconditions SU's and
sells them real cheap, if I remember correctly a Dutch friend bought a
pair of HS4's for £100 quid(approx $150) at the Spitfire Weekend in
Holland this year. that didn't include the manifold but I don't think he
charges too much for the whole lot. The carbs I have seen of his are very
smart, all the bits are aqua blasted and any bare steel is plated(nickel I
think).
I haven't got his name or number with me, but I have it at home if anyones
interested.
