Holley Short Spring Question
I have the Holley spring kit and Lars talks about a short white spring. The only spring in this kit is white, but I would not say it's short, it is about the same size as the others.
I take it this is the spring he is talking about.
If I am looking down the carb and i rev the motor, should I see the secondarys open?

Google "holley carb tuning" and you will learn that vacuum secondaries only work under load and are tested at WOT on a dyno.
What problem are you trying to fix? As your Holley carb instruction manual may explain, too light of a secondary spring can cause other problems.

Wish I had the quick change spring kit since changing it out is a painHere is a chart from my Holley tuning book, kinda hard to see from this scan so I can e-mail it if you like
BTW It only lists one white spring and 2 yellow, one of which is short.

There are 2 white springs in the kit - one tall (regular size) and one short. The short white is the softest spring and will give you the quickest secondary opening.
