If I am interpreting correctly, you have the original Hitachi Carb.

If that is correct, then you shouldn't adjust the fuel mixture screw. It's located behind a blocking pin that has to be tapped out with a punch and hammer. If you are adjusting that screw, you need to have a wide band Oxygen sensor and air/fuel mixture gauge to set the mixture.

some of the settings that you CAN adjust are: cold Idle, Hot Idle, and... I think that's it.

if the pin is still in it, then it hopefully is still set correctly. Are you sure that all of your vacuum lines are in proper order? If the vacuum lines are not in the right place or if they are old and not making a good seal, then it will run bad. If you have a vacuum leak on any of the hoses, or at the throttle body or intake manifold, then it will make it run lean. If your EGR system is not working right and is stuck open it will make it run too rich. If your EGR valve is leaking it will run too lean. If your fuel tank vent is blocked or obstructed the fuel pump will have a hard time sucking fuel from the tank and you will run lean. If your one way valve on the Deceleration "Mixture Control Valve" is sticking then you will run too lean or rich when decelerating. If your Hot idle compensator in the air intake case (hat) is malfunctioning you will run too rich or lean when at idle.

There are so many things that control your air fuel mixture that the odds of it being the mixture screw on the throttle body that has a locking pin over it, is pretty minimal. If you insist on setting the mixture screw, then first install a wide band oxygen sensor in place of the stock oxygen sensor on the exhaust. Next get an air-fuel mixture gauge to tell you how lean/rich/stoiche the exhaust is and hook it up to your new Oxygen sensor. Warm up the engine and put the vehicle on a rolling dynometer and run it at mid RPM range. Check your A/F gauge and adjust the mixture screw untill it reads stoiche.

Bienvenido al foro, Hugo!
Segun entiendo, quieres ajustar el carburador para que quede como de fábrica. Estos carburadores aparentemente no se descalibran, ya que vienen sellados de fábrica con un pasador.
Si aún quieres intentar ajustarlo, tienes que hacerle un barreno pequeño al extremo cerrado donde está el pasador y golpear éste usando un clavo y martillo.

Mi Samurai tiene un Weber 32/36 DGV instalado (lo compré así) que no me da problemas para nada.

Normalmente la computadora ajusta la mezcla automaticamente a través de un solenoide dentro del carburador (mixture control solenoid valve o MCSV (válvula solenoidal de control de mezcla).
Según recuerdo, si desajustaron el tornillo externo, requiere el uso de un "Dwell Meter" para su recalibración.
Yo sugiero que lentamente cierres el tornillo hasta que asiente suavemente (anotando la cantidad de vueltas que le díste) y abrirlo exactamente 2 vueltas, ya que leí en otro foro que era la cantidad de vueltas que tenía de fábrica.
Si corre peor, puedes volver a ajustarlo a la cantidad de vueltas que tenías antes.

Normally, the ECU adjusts fuel mixture automatically via the mixture control solenoid valve (MCSV) inside the carburetor.
If I recall correctly, if they maladjusted the outer mixture control screw, you'll need a dwell meter for recalibration.
I suggest you turn in this screw slowly until it seats gently (remember the number of turns you gave it) and turn it out exactly 2 turns, which is what someone posted on another forum was their stock setting.
If it runs worse, you can always turn it back to your default setting.

8- Remueve el sello de goma del conector "duty check" y conecta el terminal positivo del duty meter (lo mismo que dwell meter) al cable azul/rojo y el terminal negativo al azul/verde.

9- Enciende el motor y correlo a 1500-2000 RPM por 30 segundos y luego dejalo en baja.

10- Con el motor corriendo en baja, ajusta el tornillo de mezcla lentamente en pequeños incrementos dejando tiempo para que la aguja del metro estabilice luego de girar el tornillo para lograr obtener una lectura de 10-50 en el metro. Si esta muy baja la lectura, gira el tornillo a la izquierda (aflojar); si esta muy alta, gira a la derecha (ajustar). Luego de obtener una lectura de 10-50, verifica la baja y ajustala si es necesario.

Este procedimiento solo se puede llevar a cabo si el sistema de retroalimentación (feedback system) que compone el carburador con todos sus sensores, cablería y la computadora (ECU) esten funcionando bien.

Espero hayas entendido mi pobre traducción, ya que no escribo muy bien el español (soy puertorriqueño, despues de todo ;)
