Product Overview
Replace a worn, clogged, leaking, or poorly performing carburetor with this 26mm replacement carburetor with fuel tube, designed for select Yamaha Timberwolf 250 YFB250 and YFB250FW ATV applications from 1992–2000.
The carburetor controls the air and fuel mixture entering the engine. A properly working carburetor can help improve starting, idle stability, fuel delivery, throttle response, acceleration, and overall ATV performance. If your Yamaha Timberwolf 250 has hard starting, rough idle, fuel leakage, hesitation, poor throttle response, sluggish acceleration, or unstable running, replacing the carburetor may help restore smoother operation.
This carburetor features a 26mm manifold intake diameter, 54mm mounting hole spacing, and 41mm air intake diameter. Please compare your original carburetor’s OEM number, intake size, air filter connection, mounting hole spacing, choke setup, throttle cable connection, fuel inlet position, fuel tube routing, gasket shape, and overall body design before ordering.
