Hi,
Been awhile since I've posted.
About 15 years ago I converted to HS6 SU's. They came set up for TR6 by
Ted Schumacher with ZH needles (from Volvo 122S, I think) and red springs
and that's worked fine for me. My engine has stock cam, intake manifold
reworked a la Kastner's performance manual, ported and cc'd head, +.020
cylinders, tube header and free flow exhaust.
A few years later I helped a pal install an SU conversion sourced from Joe
Curto of NYC, who is one of the best on constant depression carbs. Don't
know what he might be using now, but on that setup he used the stock needles
for the HD SU on the Austin Healey 3000, Mk III. Can't remember what
springs were used. This TR6 was bone stock. They worked just fine.
Jim
