How to read carb calibration chart?

I’ve learned a lot from this thread. Hopefully sometime this week I can order a few parts and find some time to piddle with it. I’ll come back in here and post what I do.
Thanks guys.
I think the metering rods are about 12 bucks and a set of Springs is around $9 if I'm not mistaking.. Remember don't let us cyber spend too much of your money... that likes to happen out here...
