How to Adjust the Carburetor Mixture to Be Richer or Leaner?

[Adriel]

Carburetor mixture adjustment: tightening the screw makes the mixture leaner (clockwise), while loosening it makes the mixture richer. Carburetor-related information: 1. Classification: Carburetors are divided into simple carburetors and complex carburetors. They can also be classified as downdraft and sidedraft carburetors. Based on the throttle type, carburetors can be further categorized as rotary and slide types. 2. Rotary throttle: A rotary throttle is a disk-shaped throttle that rotates around an axis between the carburetor throat and the intake pipe, altering the flow area of the intake passage. Slide throttles have a barrel or plate-shaped throttle that moves up and down at the throat to change the passage area. This type is commonly used in motorcycle carburetors. 3. CV type: There is also a hybrid carburetor that combines both types, with a manually controlled rotary throttle and a diaphragm-controlled slide throttle, often used in motorcycles and referred to as the CV type.
