Products Description
Professional Carburetor Fuel Metering Assembly fits STIHL HS80 Hedge Trimmer
Precision-Calibrated Diaphragm-Type Induction Module featuring Dual-Circuit Atomization Logic for 2-Stroke Powerhead Restoration.
Chain saw Carburetor for STIHL HS80
The HS80 fuel metering assembly constitutes a high-precision diaphragm-type carburetor engineered for the systematic air-fuel management of STIHL professional hedge trimmer powerheads. Utilizing an advanced dual-circuit metering architecture, it features independently tunable high-speed and low-speed fuel circuits that allow operators to precisely calibrate the stoichiometric ratio across the full RPM band. The integrated diaphragm-pump mechanism ensures consistent fuel delivery regardless of machine orientation, maintaining reliable operation during the complex multi-angle positioning required in professional topiary and hedge sculpting. Purpose-calibrated as a direct OEM-standard replacement, this module restores factory-spec cold-start behavior, throttle response, and idle stability in HS80 series equipment.
Technical Profiles & Materials
Diaphragm-Pump Fuel Delivery Logic ：Pulse-driven polymer diaphragm relies on crankcase pressure to stabilize fuel chamber levels. It delivers consistent fuel supply even during extreme multi-angle trimming, effectively avoiding fuel starvation and stalling.
Dual-Circuit Calibration Interface： Independent H/L needle valves with locking detents support on-site fine tuning. Easily calibrated for altitude changes, seasonal fuel variations and new engine break-in for optimized throttle performance.
Precision-Cast Alloy Chassis ：Premium zinc-aluminum die-cast body offers solid dimensional stability under frequent temperature shifts. Highly resistant to ethanol corrosion, extending service life with modern blended fuels.
Integrated Fuel Screening ：Built-in stainless steel fine mesh filter blocks tank debris and impurities. It ensures unobstructed fuel flow at full throttle, maintaining steady engine output during heavy-duty trimming work.

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.
