How to Adjust the Carburetor to Optimal Condition?

[Kenny]

You can use the three-high three-low method, which involves first adjusting the mixture ratio to make the engine speed reach its highest, then adjusting the idle speed to make the engine speed reach its lowest point, and then adjusting the mixture ratio again. Repeat this cycle three times, and finally slightly increase the idle speed. This way, the carburetor of the vehicle can operate at its optimal condition. There are usually two types of carburetor mixture ratio screw adjustments, with the actual effects after adjustment being: 1. Air-adjusting type: Turning clockwise to tighten increases the richness of the gasoline mixture, while turning counterclockwise reduces the richness and increases air. 2. Fuel-adjusting type: Turning clockwise to tighten increases the air intake and reduces the fuel intake, i.e., leans the mixture; turning counterclockwise reduces the air intake and increases the fuel intake, i.e., enriches the mixture.
