[6pack] SU HS6 on TR6 Needles & Springs

[Dave More]

I have some HS6's on my car and the car runs well with them with the exception
of a bit of a minor stumble off idle. Mixture is correct, the carbs are
balanced, dashpot oil is the correct level, so I'm starting to think springs
and/or needles.

Can any of you running these carbs tell me which springs and needles you're
running?

I got these carbs from Jeff at Paltech so I'll be getting hold of him as
well.

Oh, and FWIW I'm also at about 4000' altitude.
