Products Description
Brush Cutter Needle Valve Set
Precision Fuel Metering Component for Small Engine Carburetors
The needle valve set is a critical component of the carburetor fuel system on brushcutters, trimmers, and other outdoor power equipment. The inlet needle valve (also known as the float needle or fuel inlet valve) regulates fuel flow into the carburetor's float chamber or metering chamber, maintaining the correct fuel level for stable engine operation and reliable starting . A worn or damaged needle valve can cause flooding, fuel starvation, rough idle, hard starting, or erratic engine performance . Available in OEM-spec configurations from leading manufacturers, this replacement set restores proper fuel metering and extends engine life.
Technical Profiles & Materials
Precision Fuel Regulation – The needle valve works with the float or metering lever to control fuel entry into the carburetor. A metal body with a fuel-resistant sealing tip ensures reliable shut-off and prevents leakage . When the float chamber reaches the correct fuel level, the float rises and the needle valve blocks the fuel inlet .
OEM-Spec Compatibility – Available for a wide range of brushcutter models and engine platforms. Genuine Honda parts are supplied under part number 16019-ZM3-004 (also 16019ZM3004) for GX25 and GX35 4-stroke engines . Shindaiwa compatibility includes part number 60908-98360 for B3000 and C2510 brushcutters . Metabo HPT models CG33EJ, CG40EJ, CG47EJ, and CG47EY use part number 6685215 .
Cross-Platform Compatibility – Multi-brand needle valve kits are available for Tillotson, Walbro, and Zama carburetors. The 82-75-7 valve fits Tillotson HS series carburetors and cross-references to OEM numbers TILLOTSON 34-188, WALBRO 82-26, and ZAMA 18002 . Zama-compatible needle valves are available for C1Q-S41A, C1Q-S41B, C1Q-S41C, C1Q-S42, C1Q-S42A, and C1Q-S42B series carburetors .
Durable Construction – Manufactured from high-quality metal with a fuel-resistant sealing tip, designed to withstand exposure to gasoline and ethanol-blended fuels. The robust construction ensures long service life and reliable sealing performance in demanding outdoor conditions .
Professional Service Recommendation – Workshop manuals specify that the seat, needle valve, and lever arm should be replaced together during carburetor overhaul. The seat should be pressed in level with the carburetor housing using a suitable punch (Ø 4.5 mm) . The needle valve's sealing tip should be checked for wear; replace damaged parts with new components .

FAQ
Q: How do I confirm which needle valve fits my brushcutter?
A:Check your engine model number or carburetor model stamped on the carburetor body. Honda GX25/GX35 engines use 16019-ZM3-004 . Shindaiwa models use 60908-98360 . Metabo HPT models use 6685215 . For Walbro, Tillotson, and Zama carburetors, cross-reference OEM numbers such as Walbro 82-26, Tillotson 34-188, and Zama 18002 .
Q: What are the symptoms of a worn needle valve?
A: Common symptoms include fuel leaks, flooding, hard starting, rough idle, flat spots during acceleration, and erratic engine performance . The needle valve may also stick open or fail to seal, allowing fuel to continue entering the carburetor. Workshop manuals recommend replacing the seat, needle valve, and lever arm together if any wear is detected .
Q: Should I replace just the needle valve or the complete set?
A: Professional workshop manuals specify that the seat, needle valve, and lever arm should be replaced at the same time during carburetor overhaul . The seat should be pressed in level with the carburetor housing using a suitable punch (Ø 4.5 mm) . Replacing all components together ensures proper fuel metering and prevents premature failure of new parts.
