Extolern Carburetor for Redmax EBZ8500/EBZ8500RH Backpack Blower — Aluminum Replacement with Gasket & Adjustment Screwdriver

Extolern's precision-machined aluminum alloy carburetor replaces worn units on Redmax EBZ8500/EBZ8500RH and compatible Husqvarna 580-series backpack blowers to restore fuel efficiency and steady engine performance.

When a backpack blower starts sputtering, uses excess fuel, or becomes hard to start, the carburetor is often the culprit. Extolern designed this replacement carburetor and accessory kit for Redmax EBZ8500 and EBZ8500RH models — and for Husqvarna models that share the same platform — using tightly machined aluminum alloy parts to improve fuel atomization and durability. The kit includes the carburetor, gasket, choke rod and a dedicated adjustment screwdriver so you can install and fine-tune the unit for optimal running characteristics.

How does this carburetor affect blower fuel use and power?

Replacing a degraded carburetor can reduce excess fuel consumption and help the engine run more efficiently across idle and full-throttle ranges. Extolern’s aluminum alloy construction and precise machining promote consistent fuel-metering and smoother throttle response.

• Improved atomization reduces raw fuel waste at mid and high throttle.
• Tighter tolerances limit air leaks that cause lean/rich running conditions.
• Gasket included to ensure a sealed intake and consistent vacuum signals.

Is this a direct fit for my Redmax or Husqvarna backpack blower?

The unit is made to match Redmax EBZ8500 and EBZ8500RH carburetor specifications and is compatible with Husqvarna 580BTS and 580BFS units that share the same mounting and fuel connections. Confirm part fit by comparing mounting bolt pattern and fuel/choke linkage before installation.

• Designed for Redmax EBZ8500 / EBZ8500RH models.
• Compatible with Husqvarna 580BTS and 580BFS where fittings match.
• Includes gasket and choke rod to match original mounting hardware.

What comes in the box and how do I adjust it after installation?

The package contains the carburetor, a replacement gasket, choke components and a special small screwdriver for the mixture screw. After mounting, set the fuel-mix screw to the recommended baseline and then fine-tune in small increments (about 1/4 to 1/2 turn adjustments) until idle and acceleration feel stable.

• Packing list: carburetor, gasket, choke rod/hole, adjustment screwdriver.
• Start with baseline mixture, then adjust 1/4 to 1/2 turn for tuning.
• Listen for smooth idle and immediate throttle response; avoid over-rich settings.

How durable is this replacement compared to an OEM unit?

Extolern uses high-grade aluminum alloy and precision machining to deliver a robust body and accurate internal passages. While longevity depends on operating conditions and fuel quality, the construction aims to match or exceed the service life expected from stock carburetors when properly installed and maintained.

• Aluminum alloy body resists corrosion and warping from heat cycles.
• Precision-machined surfaces reduce wear and improve sealing with the gasket.
• Supplied hardware helps avoid common installation gaps that shorten service life.

Who is this for? This Extolern carburetor kit is for landscapers, maintenance pros, and property owners who use Redmax EBZ8500/EBZ8500RH or compatible Husqvarna 580-series backpack blowers and need a reliable replacement part. Choose this kit if your blower shows rough idling, poor throttle response, increased fuel use, or if the original carburetor is leaking or damaged. It’s also suitable for technicians who want a ready-to-install kit with the adjustment tool and gasket included.
