化油器的怠速理论与调节步骤（The idle theory and adjustment procedure of carburetor） The idle theory and adjustment procedure of carburetor This article will be included in the book of the book, whether the depth and breadth can be included in the textbooks, which will bring good news to the users of motorcycles, motorcycles and motorcycles.

Some GY6 engines vibrate between 1300 and 1400r/min, and it is best not to adjust the idle speed at this speed. Four blunt gasoline engine to maintain regular idle rely on fuel, air, internal resistance, the rotating speed of ignition Angle ~ ~ ~ ~ effect, manually adjust the four, plus the effect of speed effect, determines the engine idle speed and steady state, as well as the engine startup performance. I. fuel oil: Decided to idle is idle carburetor oil fuel supply steam screw, on vacuum membrane carburetor, idle oil steam adjusting screw in the left side of the carburetor, is a hidden copper screws, head to the left horizontally, slender usually use the word, and from the left of the carburetor, screw the implementation regulation.
