[TR] HS2's /needles/springs

[Joe Curry]

Harve,
Since the HS2's were never placed on a Spitfire1500 at the factory, it is
hard to say how the AN needles will work.  I tried a pair on a 1500 a few
years ago and found that there was a flat spot about 4000 rpm and the car
accelerated up to that point just fine but when it reached that magic point,
it was if someone shut off the ignition switch.  If I lifted a bit, it would
pick back up.

I tried a few other needles but never did get it to perform the way I
thought it should.

Joe

I have a US 1500 1978 Triumph Spitfire with HS2's (tagged AUC9831 &
AUC9831R - handmarked on the top AUD9253 & AUD9256) I use K&N filters and
a 4-2-1 exhaust manifold. I am using AN needles. I have no idea what
springs are in place. 

My questions: 

1) Is the AN needle okay for street use? 
2) What springs do I need, and how do I tell what I have? 

tks. harve
