  Q:

  How to remove and install a carburetor on Mazda B2200?

  A:

  To dismount and refit the carburetor air cleaner and duct, take off the air cleaner and duct, first disconnect the accelerator shaft from the throttle lever. Likewise, disconnect the fuel supply and return lines; electrical leads from the throttle solenoid and deceleration valve; the carburetor-to-distributor vacuum line. Furthermore, disconnect the throttle return spring (if applicable), the choke cable, and the cruise control cable (if applicable). Using a small socket or thin wrench for better access, remove the carburetor attaching nuts from intake manifold studs and take out the carburetor. For installation, place a new gasket on the manifold and install the carburetor. Tighten the attaching nuts. Reconnect the throttle return spring, accelerator shaft, electrical leads, distributor vacuum line, and fuel lines. Adjust the choke and cruise control cables. Reinstall the air cleaner and duct. Turn on the engine to check for fuel leak Break down the carburetor in a clean area. Keep similar objects separate. Wash all parts in carburetor solvent except for the float assembly. Rinse and dry the components with water as necessary. Examine the part for wear and damage, especially the float needle, float hinge pin, throttle and choke shaft bores, idle moisture adjusting needles and accelerator pump check valves, replacing as necessary. Carburetor overhaul kits are useful for replacement parts in your carburetor. Always replace all gaskets and other key parts as performance issues can occur when not done. Adjustments consist of setting and clearance of the fast idle cam for type I and II engines, checking and adjusting idle speed and mixture where necessary, measuring float levels and fuel levels, checking accelerator linkage, checking secondary throttle valve clearance, making choke adjustments. Finally, examine the idle switch for proper voltage readings.

  Q:

  What are the steps for replacing the carburetor on Mazda B2000?

  A:

  The Mazda Rotary Pick-Up has a 4-barrel downdraft carburetor, while the piston engines have a 2-barrel downdraft carburetor. Starting on piston engines, remove the air cleaner and duct. Then, disconnect the accelerator shaft from the throttle lever. After that, disconnect and plug both the fuel supply and return lines, then disconnect the leads from the throttle solenoid and deceleration valve. Detach the vacuum line from the throttle spring, vacuum line, and cruise control cable if applicable, and the choke cable. Remove the nuts that attach the carburetor to the intake manifold studs. Sometimes you need a small socket with an "L" shaped hex drive, or a short, thin wrench. Attach the carburetor to the manifold after new gasket installation, then tighten its nuts. Then, reconnect the throttle return spring, accelerator shaft, electrical leads, distributor vacuum line, and fuel lines. If applicable, adjust choke cable and cruise control cable, refit air cleaner and duct, and finally start the engine and check for fuel leaks. Remove the air cleaner assembly with its hoses and mounting bracket. Disconnect the choke and accelerator cables. Disconnect the fuel and vacuum lines from the carburetor. Detach the oil line from the carburetor to the metering oil pump. If applicable, disconnect the idle sensor switch wiring. And then remove the carburetor attaching nuts or bolts, gasket, or heat insulator. The installation process is the opposite of removal, and a new gasket should be used. The float bowl should be filled with gasoline to assist starting.
