Carburetor for GX240 GX270 173F 177F Generator | Huayi 8HP 9HP 3KW 4KW 4-Stroke Engine
Complete Carb Assembly with Fuel Solenoid Wiring & Fuel Line | Direct Replacement for Honda-Style Portable Generator Engines
Generator GX240/GX270/173F/177F/3KW/4KW/8HP/9HP Carburetor
This Huayi-branded carburetor assembly is a complete fuel-system replacement engineered for 4-stroke single-cylinder gasoline engines in the 8HP–9HP (173F–177F) class, covering the widely deployed GX240 and GX270 Honda-style engine platforms used on 3KW and 4KW portable generators. Manufactured by Huayi - one of China's largest OEM carburetor producers supplying major small-engine brands - the assembly features a die-cast aluminum body, a float-bowl fuel-metering system, an integrated fuel-shutoff solenoid with pre-attached wiring harness, and a pre-cut rubber fuel line. The kit includes a replacement L-shaped throttle linkage lever and a spare metering needle jet for comprehensive carburetor overhaul in a single parts order.Designed as a direct bolt-on replacement that aligns with the OEM intake manifold stud pattern and throttle-governor linkage geometry, this carburetor restores cold-start reliability, steady idle, and fuel-efficient wide-open-throttle performance to generators serving in residential backup, construction site, and agricultural power applications.
Technical Profiles & Materials
Grade Die-Cast Aluminum Body：
The carburetor body is pressure die-cast from aluminum alloy and precision-machined at all critical interfaces - the float-bowl sealing surface, throttle butterfly bore, venturi throat, and main jet seat - ensuring consistent fuel metering accuracy across production batches. Huayi's manufacturing pedigree as an OEM supplier to generator brands means the internal passage dimensions, emulsion tube calibration, and idle-circuit drilling match the original engine manufacturer's specification rather than the approximate geometry of generic clone carburetors.
Integrated Fuel-Shutoff Solenoid with Wiring Harness：
A 12V DC fuel-shutoff solenoid is threaded into the bottom of the float bowl, with a pre-terminated two-wire harness ending in a translucent green quick-connect plug. When energized during engine cranking and running, the solenoid retracts its pintle to open the main jet fuel passage; upon engine shutdown, the de-energized solenoid extends the pintle to block the main jet, preventing hot-engine afterfire and raw-fuel dripping into the cylinder.

Products Application
Agricultural & Remote-Area Generator Power Systems
Generators powered by GX240/GX270 and 173F/177F engines are the workhorse backup power solution for homes, small retail shops, and rural properties across markets with unreliable grid electricity. When these generators develop hard-starting, surging, or fuel-leaking symptoms after months of intermittent storage, the root cause is frequently a gummed, corroded, or solenoid-failed carburetor. This complete Huayi assembly restores factory fuel-system performance in a single parts change, with the pre-attached solenoid harness and fuel line eliminating time-consuming component transfers from the old carburetor - a critical advantage for repair technicians handling multiple generator service calls per day during storm season and scheduled blackout periods.
Construction & Rental Generator Fleet Fuel Rebuilds
Construction site generators endure extreme operating conditions: continuous multi-shift runtime, high ambient temperatures near running engines, fuel sourced from job-site jerry cans with variable cleanliness, and exposure to cement dust and aggregate fines. The carburetor's float-bowl design with serviceable main jet via the bowl nut allows fleet maintenance teams to quickly clear debris-induced jet blockages without full carburetor disassembly, while the Huayi OEM-grade internal calibration avoids the lean-burn and valve-damage risks associated with generic replacement carburetors on high-runtime engines. The included spare needle jet and linkage lever reduce the variety of separate part numbers a rental-fleet parts room must stock.
Residential & Small Business Backup Generator Servicing
Farm-based generators running irrigation pumps, livestock water heaters, and grain-drying fans in remote locations depend on carburetor reliability where replacement parts delivery may take days or weeks. The Huayi carburetor's reputation for out-of-box tuning accuracy - idle speed and mixture preset close to the engine's requirement - reduces the need for on-site adjustment by operators without carburetor-tuning experience. The kit's all-inclusive format (carb + hose + solenoid + linkage + jet) ensures that the technician dispatched to a distant farm generator arrives with every carburetor-related component needed, removing the risk of a wasted trip due to a single missing connector or linkage piece.

FAQ
Q: Are you an impartial industrial components dealer or a direct China water pump factors factory?
A:We are a direct, ISO9001-certified engineering water pump components manufacturing facility and precision fluid-control factor manufacture exporter primarily based in China. We function our personal cleanroom injection molding bays, computerized ultrasonic welding arrays, computerized hydraulic stress check stations, and clean-room packaging lines, passing direct-factory wholesale price financial savings straight to your element procurement margins.
Q: Can your manufacturing unit furnish full certification forms for food-contact or consuming water compliance?
A: Yes, absolutely. For food, beverage, or scientific applications, our manufacturing unit makes use of one hundred percent virgin, un-recycled polypropylene resins accompanied by means of fabric traceability certificates. We mechanically furnish B2B purchasers with complete FDA compliance documentation, NSF-grade compound declarations, and RoHS/REACH chemical protection screening sheets to make certain clean clearance thru worldwide customs.
Q: Do you provide customization picks for distinctly corrosive fluids like sturdy acids or ozone?
A: Yes, we are a thoroughly succesful OEM/ODM supplier. For aggressive chemical or ozone environments, we can improve the 12x26.5mm valve configuration in our factory: substituting the general PP housing with top class PVDF (Fluoropolymer) and changing any steel springs with Hastelloy or whole springless gravity-ball architecture, making sure final chemical resistance.
Q: How do we impervious a pattern batch to execute computerized lifecycle and burst-pressure testing?
A: We relatively inspire complete laboratory contrast earlier than logging mass grant agreements. We can ship a pattern lot of 5-10 gadgets of our inventory 12x26.5mm take a look at valves for assessment (setup costs and DHL/FedEx air freight apply). Once the factors pass by your inner lifecycle verification and a formal wholesale quantity manufacturing contract or container run is locked in, the sampling charges are a hundred percent credited returned to your industrial balance.
