The Mikuni BS 36 carburetor is a widely-used component in the automotive industry, renowned for its reliability, performance, and versatility. Understanding the intricate workings of this carburetor is essential for maintenance, tuning, and optimization. This article presents a detailed exploded view of the Mikuni BS 36 carburetor, providing an in-depth look at its components and their functions.
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.
The float bowl serves as a reservoir for gasoline. It contains the float and float valve, which regulates the fuel level in the bowl.
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.
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.
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.
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.
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.
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.
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.
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.
Understanding the exploded view of the Mikuni BS 36 carburetor is essential for maintaining, tuning, and optimizing this critical component. By following the step-by-step assembly guide, adhering to the tips and tricks, and avoiding common mistakes, you can ensure that your Mikuni BS 36 carburetor operates at its best and delivers optimal performance.
