I think I could even lead my brother, who barely knows a screwdriver from a hammer, through a rebuild of a 4160. And over the last 40 years I've made every mistake humanly possible to make -- so I can see them coming and tell you how to avoid them. The first step, though, is to temporarily plumb a new pressure gauge right in front of the carburetor. The second step will be to conquer your fuel pressure issue. The last step will be to rebuild the carb with that kit. It's a better than fair chance that the 9psi that you were seeing resulted in the secondary flooding out by eating the needle/seat valve for lunch. So there's no sense in even touching the carb until we have a nice, clean, even 6psi feeding her.
