Echo 12300003662 Carburetor WT-409B Small Engine

Product Description

The ECHO 12300003662 is a WT-409B carburetor designed for small engine fuel delivery in handheld outdoor power equipment. The carburetor meters and atomizes fuel for proper air-fuel mixture, enabling reliable combustion under varying throttle conditions. This is an OEM-referenced replacement part intended for installation by small engine technicians and qualified service professionals familiar with two-stroke or four-stroke carburetor systems. It maintains the fuel circuit specifications required by the original equipment design.

This carburetor is suited for residential and light commercial applications where ECHO-branded handheld power equipment requires fuel system service or repair. Typical install scenarios include carburetor replacement during seasonal tune-ups, after ethanol-related fuel system degradation, or when idle and throttle response issues are traced to the carburetor assembly. Technicians servicing ECHO trimmers, blowers, or similar equipment in the field or at a service bench will find this a direct-fit replacement for the WT-409B specification.
