Check this procedure about Carburetor REMOVAL & INSTALLATION....

detailed, visual, instructions, on rebuilding a - zjlimited_52.jpg

Fig. 1: Carburetor components

  1. Disconnect the negative battery cable.
  2. Disconnect the following:
    1. Hot air tube.
    2. Vacuum hose between the one-way valve and the manifold at the manifold.
    3. Breather chamber (on air cleaner case) to intake manifold at the breather chamber.
    4. Hose from the air cleaner case to the valve cover.
    5. Hose from the carbon canister to the carburetor, at the carburetor.
    6. Throttle opener hose at the throttle opener.
  3. Disconnect the fuel line at the carburetor. Plug the end of the fuel line to prevent dust entry.
  4. Disconnect the choke and throttle control cables.
  5. Disconnect the fuel shut-off solenoid wires.
  6. Remove the carburetor retaining bolts and the carburetor. Leave the insulator on the manifold. Cover the intake manifold to prevent anything from falling into the manifold.
To install:
  1. Install the carburetor assembly onto the insulator using a new gasket. Tighten the mounting nuts to 17 ft. lbs. (24 Nm).
  2. Attach the vacuum and electrical connections.
  3. Connect the fuel lines to the carburetor.
  4. Install the air cleaner assembly and reconnect the intake air hoses.
  5. Connect the negative battery cable. Check and adjust the idle as needed.

Keep in mind that, when the carburetor is disassembled, wash all parts (except diaphragms, electric choke units, pump plunger and any other plastic, leather, fiber or rubber parts) in clean carburetor solvent. Do not leave parts in the solvent any longer than is necessary to sufficiently loosen the deposits. Excessive cleaning may remove the special finish from the float bowl and choke valve bodies, leaving these parts unfit for service. Rinse all parts in clean solvent and blow them dry with compressed air or allow them to air dry. Wipe clean all cork, plastic, leather and fiber parts with a clean, lint-free cloth.

Blow out all passages and jets with compressed air and be sure that there are no restrictions or blockages. Never use wire or similar tools to clean jets, fuel passages or air bleeds. Clean all jets and valves separately to avoid accidental interchange.

Check all parts for wear or damage. If wear or damage is found, replace the defective parts. Especially check the following:
  1. Check the float needle and seat for wear. If wear is found, replace the complete assembly.
  2. Check the float hinge pin for wear and the float(s) for dents or distortion. Replace the float if fuel has leaked into it.
  3. Check the throttle and choke shaft bores for wear or an out-of-round condition. Damage or wear to the throttle arm, shaft or shaft bore will often require replacement of the throttle body. These parts require a close tolerance of fit; wear may allow air leakage, which could affect starting and idling.
Throttle shafts and bushings are not included in overhaul kits. They can be purchased separately.
  1. Inspect the idle mixture adjusting needles for burrs or grooves. Any such condition requires replacement of the needle, since you will not be able to obtain a satisfactory idle.
  2. Test the accelerator pump check valves. They should pass air one way but not the other. Test for proper seating by blowing and sucking on the valve. Replace the valve if necessary. If the valve is satisfactory, wash the valve again to remove breath moisture.
  3. Check the bowl cover for warped surfaces with a straight edge.
  4. Closely inspect the valves and seats for wear and damage, replacing as necessary.
  5. After the carburetor is assembled, check the choke valve for freedom of operation.

Hope this helps.

Having truble with my carburater on a 1984 ford 1500 how can i rebuild it

You can order rebuild kits at your local auto parts store. Tell them the model, and engine size. They will also need some details about your carburetor, such as - 4 barrel or 2? Follow the instructions in the kit exactly, and replace all the gaskets/seals, whether they look like they need it or not.
