: I posted a reply to my own message last
: night and "saw it" after
: posting. This a.m. it is gone? Was it
: deleted or am I the victim of
: high-technology gone wrong?
:
: Regardless, I looked up the profile of
: the 6J needle that Glen mentioned and
: then visited Paul T's web site where I
: keyed in the major (10th digit) needle
: diameter for stations 2, 7, and 13.
:
: It turns out that the 6J Stromberg
: needle is fairly close to the SU BB3
: needle. Since apparently you can get a
: real 6J needle this is not helpful.
: However, I did this as an exercise to
: show that to a certain degree you might
: be able to find and adapt SU needles to
: provide the Stromberg profiles you are
: after. It will involve some detective
: work but might be possible.
:
: Again... surely there is a reason this
: isn't suggested more often so please
: feel free to point out what I am
: missing.

: OK... I have a couple of questions.
:
: First, Glen, what is (or was) that
: device before it became your needle
: tool? Then... how do you use that
: tool (not the micrometer... the whole
: thing)?
:
: I don't have Stromberg parts around
: here to measure so again, I fall back
: to SUs. These are more naive questions
: and suggestions. I KNOW this has been
: asked before by others so please feel
: free to correct me and put me straight.
:
: With SUs needles the taper diameter is
: measured in thousandths of an inch
: every 1/8" along the length of the
: needle and I am assuming that is the
: way Stromberg needles are also
: characterized. If the inside diameter
: of Stromberg and SU jets are the same,
: could you not use SU needles in
: Stromberg carbs? Sure you would
: probably have to bush or turn down the
: mounting stem diameter but if the jets
: are the same size it could open up a
: whole world of possible needles.
:
: Since the link to Paul T's needle page
: was posted earlier, there is another
: one that you might find helpful. Once
: again, this is for SUs but it may prove
: useful (if not now... in the future).
: http://www.mintylamb.co.uk/suneedle/
: The Mintylamb utilities will let you
: graphically compare different SU
: needles. This gives you an idea how
: lean or rich one will be compared to
: another at various amounts of carb
: piston lift.
