How to fine tune metering rods? Power piston springs? i will start with stock settings.
You can measure the size of the different steps on the metering rods and then decide if you want the part throttle cruise richer or leaner, same thing at WOT the bottom small size step
You compare your rod sizes and then decide if you want to go richer, smaller steps, or larger with thicker step rods
As far as the springs if it ain't broken don't fix it, in other words if it drives alright now work on the mixture first at part throttle and then at wide open throttle and then if you want, look at changing those springs. At W.O.T. you secondary jets come into play also
if it is good at part throttle cruise and lean at WOT change the secondary jets up one size first and test it

Many things influence the carb., unlike the new cars with EFI
