Components and Functions

1. Carburetor Body

The carburetor body is the main housing that holds all the other components together. It provides a sealed chamber for the air/fuel mixture and contains the throttle valve, which controls the amount of air entering the engine.

2. Float Bowl

The float bowl serves as a reservoir for gasoline. It contains the float and float valve, which regulates the fuel level in the bowl.

3. Float and Float Valve

The float is a hollow metal or plastic device that floats on the fuel in the float bowl. As the fuel level rises, the float rises with it, pushing against the float valve to shut off the fuel supply.

4. Main Jet

The main jet is a small orifice located in the center of the carburetor body. It controls the amount of fuel that flows from the float bowl into the air stream at higher throttle openings.

5. Pilot Jet and Air Jet

The pilot jet and air jet work together to control the amount of fuel and air that flows into the engine at low throttle openings. The pilot jet delivers a constant amount of fuel, while the air jet controls the amount of air that mixes with it.

6. Needle Jet

The needle jet is a tube located in the center of the carburetor body. It controls the amount of fuel that flows from the main jet into the air stream at mid-range throttle openings.

7. Air Corrector Jet

The air corrector jet is located on the side of the carburetor body. It provides additional air to the air stream at higher throttle openings, helping to lean out the air/fuel mixture.

8. Power Jet

The power jet is an optional component that provides an additional burst of fuel when the engine is under load. It is typically used in high-performance applications.

9. Throttle Valve

The throttle valve controls the flow of air into the engine. It is operated by the gas pedal and can be opened or closed to regulate the engine speed.

10. Choke Valve

The choke valve is a manually-operated lever that closes off the air intake to the carburetor. It is used to enrich the air/fuel mixture during engine starting.

Step-by-Step Assembly Guide

1. Disassemble the carburetor: Remove the carburetor from the vehicle and disassemble it into its individual components.
2. Clean the components: Thoroughly clean all the carburetor components using a carburetor cleaner.
3. Inspect the components: Inspect the carburetor components for wear, damage, or corrosion. Replace any damaged or worn-out parts.
4. Assemble the carburetor: Assemble the carburetor components in the reverse order of disassembly.
5. Adjust the idle speed: Once the carburetor is assembled, adjust the idle speed using the throttle stop screw.
6. Test the carburetor: Start the engine and test the operation of the carburetor. Make any necessary adjustments for optimal performance.

Tips and Tricks

• Use genuine Mikuni parts for the best performance and reliability.
• Regularly clean the carburetor to prevent clogging and ensure optimal operation.

Common Mistakes to Avoid

• Overtightening the carburetor bolts: Overtightening the carburetor bolts can damage the carburetor body.
• Not sealing the float bowl properly: A loose float bowl can lead to fuel leaks.
• Using the incorrect carburetor size: Using a carburetor that is too small or too large for the engine can lead to performance problems.
• Leaning out the air/fuel mixture too much: A lean air/fuel mixture can cause engine damage.
• Not cleaning the carburetor regularly: Clogged carburetors can lead to engine problems and poor performance.
