Fuel filter layerFuel filter layer inside the carburetor, if there is no filter element in your fuel tank or the filter element is dirty. The filter screen of the carburetor will be blocked first, resulting in poor oil intake or insufficient internal pressure resulting in insufficient oil supply. When the filter layer is removed, you can see a relatively large oil inlet channel, and the filter layer can block relatively large dust. Small particles cannot be filtered out by the filter layer |
The triangular oil needleThe triangular oil needle plays the role of pressure regulation and sealing. The triangular oil needle controls the amount of oil entering through the movement of the adjustment rod. The damage of the triangular oil needle is irreparable. |
