1. Part Number: 1406-600, 1406. 2. Compatibility: Matching with various intake manifolds. For small and some large engines to get good street performance and fuel economy. Precautions for installing the carburetor 1. Before installation, the fuel tank should be cleaned, as impurities such as gum, moisture, and rust tend to accumulate inside the tank. These impurities may block the oil pump filter screen and affect the normal supply of fuel. 2. Due to long-term transportation, the position of the oil float may change. Because this material is copper, you can adjust the oil level by checking the window. 3. If you find oil leakage in our carburetor, you can clean it. We have tested all of our carburetors and found that they contain oil. If left for a long time, some chemical reactions may occur. Cleaning can improve this issue. 4. Idle speed problem: check whether the idle speed screw is fully retracted. If it is fully retracted, it will not turn and there will be no idle speed. You can adjust the idle speed screw and the mixed gas screw to see if that solves the problem.
