i realize that i have to tinker with the setting but what i don't know how to do is to mess with floats and changing jets and any of the other stuff that i consider more in depth.
Floats adjustments and jet changes are not in depth (Nor is a rod swap) and they are the most basic of tuneing on carbs. You just cut yourself out of the picture for touching a carb.
Exp. in twisting the screws counts for allmost absoultely nothing on how to tune a carb.
If you purchase a Holley, be prepared to get a box of jets.
If you get an Edelbrock/Carter, be prepared for a jet and rod kt.
