How do I know if my carburetor is too small?
If the carburetor is too small, it restricts airflow into the engine. The cylinder can’t fill up all the way. This starves the engine and results in slow acceleration and a lack of top-end power. A larger displacement engine running at higher rpm will require more air and fuel.
What does the air screw do on a Mikuni carb?
The air screw can be located either near the back side of the carburetor or near the front of the carburetor. If the screw is located near the back, it regulates how much air enters the circuit. If the screw is turned in, it reduces the amount of air and richens the mixture.
