Troubleshooting & FAQ
How do I know if my carburetor needle needs replacing?
Symptoms of a failing carburetor needle include fuel overflowing or leaking from the carburetor, engine flooding, difficulty starting, poor or unstable idle, and a strong smell of gasoline. Over time, the needle's tip can wear or deform, preventing a proper seal.
Is this kit compatible with all engine models from the listed brands?
This kit is designed as a direct replacement for the specific part numbers listed in the Part Number Matrix. It is critical to verify that your engine's original part number matches one of the listed equivalents before purchasing, as manufacturers use different carburetors across their model ranges.
What is the function of the carburetor needle?
The carburetor needle and seat assembly is a critical valve that regulates the flow of fuel into the carburetor's float bowl. As the fuel level rises, the float pushes the needle into the seat, stopping the flow. A proper seal ensures the engine receives the correct amount of fuel without flooding.
