To adjust the air-fuel mixture on a 1985 Toyota 22R carburetor, locate the mixture screw, typically found on the side of the carburetor. Start the engine and allow it to reach operating temperature, then slowly turn the mixture screw clockwise to lean the mixture and counterclockwise to enrich it, listening for changes in engine RPM. Aim for the highest stable RPM, then turn the screw back slightly to ensure smooth operation. Finally, secure the adjustment and double-check by test-driving the vehicle.
First, you will want to be sure that it isn't flooding. Be sure that the automatic choke is working properly. Set the timing to factory specifications. Then you can only adjust the idle fuel air mixture. If it continues to run rich then the carburetor is most likely the fault.

To adjust the carburetor float on a 1990 Isuzu pickup, first, remove the carburetor from the engine and detach the float bowl. Check the float height by inverting the carburetor and measuring the distance from the float to the gasket surface; it should typically be around 14-16 mm. If adjustment is needed, bend the float arm gently until the correct height is achieved. Reassemble the carburetor and reinstall it on the engine, ensuring all connections are secure.
To adjust the two-barrel carburetor on a 1972 Dodge pickup with a 360 engine, start by ensuring the engine is warm and idling. Adjust the idle mixture screws gradually, turning them in or out until you achieve the highest RPM at idle, then set the idle speed to the recommended specification (usually around 600-700 RPM). Finally, check for smooth acceleration and make minor adjustments as necessary. Always refer to the service manual for specific tuning guidelines and specifications.

I suggest checking out the fuel filter first, it may be clogged and not supplying enough gas to the engine.
