HUZTL FS56RC Carburetor Replacement for Stihl FS40C/FS50C/FS56C/FC56C/FS70C — Direct Zama C1M-S267 Fit + Repair Kit

HUZTL FS56RC is a complete replacement carburetor kit built to fit Stihl FS40C, FS50C, FS56C, FC56C and FS70C trimmer engines as a direct swap for Zama C1M-S267 / 4144 120 0608.

If your small 2-stroke Stihl brushcutter or trimmer is running poorly, flooding, idling roughly, or not starting, the carburetor is often the culprit. This HUZTL FS56RC kit includes the carburetor plus essential consumables — gaskets, filters, primer bulbs, spark plug, fuel line and mounting parts — so you can replace the component and return the engine to reliable operation without sourcing separate pieces.

How will this carburetor restore my trimmer's performance?

The replacement unit re-establishes correct fuel and air metering, which helps steady idle, consistent throttle response and easier starting. It’s manufactured to match the Zama C1M-S267 interface and jetting pattern used by many Stihl small-engine models.

• Direct-fit design for Zama C1M-S267 / part 4144 120 0608.
• Improves inconsistent idle and hard-start symptoms when original carburetor is worn or clogged.
• Includes new gaskets and seals to prevent leaks and vacuum loss.

Which Stihl models and cable types are compatible with this part?

This HUZTL FS56RC kit is intended for Stihl FS40C, FS50C, FS56C, FC56C and FS70C where the factory used the C1M-S267-style carburetor. It uses a plastic throttle cable connection — confirm your machine’s cable end before ordering.

• Compatible: FS40C, FS50C, FS56C, FC56C, FS70C when equipped with C1M-S267 configuration.
• Not compatible with metal-type throttle cable fittings; that requires C1M-S207 (part 4144 120 0603).
• Check existing carburetor part number or cable end shape to ensure fitment.

What comes in the kit and why each part matters?

The kit supplies the carburetor plus fresh consumables so you can complete the repair in one visit. Replacing worn gaskets, primer bulbs and the fuel filter prevents future air or fuel restrictions that can undermine a new carburetor.

• 1 carburetor (HUZTL FS56RC) matched to Zama C1M-S267 specs.
• 2 gaskets, 1 air filter and 1 fuel filter to ensure sealed, clean operation.
• 2 primer bulbs, 1 spark plug, 1 fuel line, 2 grommets and 1 adjustment tool for installation and tuning.

How do I install and tune the replacement carburetor safely?

Installation requires basic mechanical skill: remove the old carburetor, transfer any necessary linkage, fit new gaskets and hoses, then use the supplied adjustment tool to set idle and mixture. Work with a clean workspace, follow manufacturer torque and routing recommendations, and make small screw adjustments while the engine is warm.

• Disconnect spark plug before work to prevent accidental start.
• Replace gaskets and fittings exactly as packaged to avoid air leaks.
• Use the adjustment tool to fine-tune idle and mixture after installation.

Who is this for: This HUZTL FS56RC carburetor kit is aimed at homeowners, landscapers and small-engine repairers who need an affordable, single-purchase replacement for Zama C1M-S267/4144 120 0608-style carburetors on compatible Stihl trimmers. It’s especially useful if you want a full set of installation parts in one box — but check your throttle cable end type first to confirm compatibility.
