ZAMDOE replacement carburetor for Husqvarna chainsaws (503280316 / 574331601 etc.)

The essentials

If your Husqvarna chainsaw is starting to feel unreliable at idle, running unevenly, or refusing to behave the way it used to, a carburetor swap is often the first practical repair people look at. This ZAMDOE carburetor is sold as a replacement unit for specific Husqvarna models and a set of Tillotson carburettor applications, using listed part numbers such as 503280316 and 574331601 (among others).

On paper, the pitch is straightforward: it’s designed to replace the original carburettor, and the pack also includes several fitting items so you’re not left scrambling for consumables. That said, carburettor compatibility and setup matters quite a lot—so if you’re not comfortable double-checking the right fit and working through a basic install, it can be more hassle than it sounds.

What it’s for (and what to expect)

This is a gasoline chainsaw carburetor intended for certain Husqvarna 61/66/266/268/272/272XP and related variants, plus Tillotson HS-254B, HS-260A and HS-260S applications. The core idea is that you remove the old carburettor and fit this replacement unit in its place. The brand also claims it’s easy to use and install.

A helpful way to picture the day-to-day use: imagine you’ve cleaned the saw, verified the fuel system isn’t obviously blocked, and you still get inconsistent running—then swapping the carburettor can restore more normal throttle response. Of course, if the real issue is air leaks, worn fuel lines, or a clogged fuel filter, a carburettor alone may not fully fix it, so it’s worth diagnosing logically.

Compatibility: the bit you must verify

Because this is a replacement part, compatibility hinges on the exact model/part numbers, not just the general saw brand. The listing explicitly advises you to verify the images and dimensions carefully before purchase.

From the information provided, the carburetor is described as suitable for: - Husqvarna chainsaws including models such as 61, 66, 266, 268, 272, 272XP, 281, 288, 288EPA, 281XP, 288XP - Tillotson HS-254B, HS-260B, HS-260A and HS-260S (the listing mentions HS-260A/HS-260S and also HS-260S) - It also references an air filter fit for Husqvarna air filter part numbers 501807101, 501807105 and 501807102, but that doesn’t automatically mean your saw needs the filter changed too.

It’s not for you if you’re hoping for a “universal” carburettor that works across random chainsaws. Better avoided unless you can cross-check your saw’s existing carburettor/part numbers and match what the kit is meant for.

What’s included in the kit (and why that matters)

One practical strength here is the included parts list. Alongside the carburetor, the package includes: - 5 gaskets - 1 spark plug - 1 spring - fuel line - 2 fuel filters - 1 shut-off valve

In real repairs, those extras can reduce friction. Instead of reusing old gaskets or searching for missing bits, you can refresh key wear parts during the same job. That’s a meaningful time-saver compared with “carb only” listings.

One limitation to keep in mind: the listing doesn’t provide any tuning settings, adjustments, or instruction specifics. Carburettor installs typically still require care with fitting and checking performance after assembly—so if you expect a fully plug-and-play outcome, you may find it falls short.

Key takeaways before buying

If you already know the part numbers you need (for example 503280316 or 574331601), and you’re comfortable verifying dimensions and the right fit, this ZAMDOE carburetor looks like a sensible repair-focused purchase. It’s also a better match if you’re doing the job yourself and want the kit extras (gaskets, filters, fuel line, shut-off valve) to make the replacement more complete.

Where it may not be ideal is if your saw’s issue isn’t actually carburetion-related. In that scenario, you might spend time and money fitting a replacement that doesn’t address the real cause. You’ll also want to avoid rushing if you’re unsure about compatibility—carburettors are one of those parts where “close enough” can still mean poor running.

Who it suits best

It makes sense if you’re working on a compatible Husqvarna model and you want a replacement carburettor kit with multiple supporting components. It suits people who are happy to check part numbers, compare images/dimensions, and carry out a straightforward mechanical swap.

It might not be a great match if you’re looking for vague “works with” guidance, or if you need guaranteed compatibility without doing that basic checking first.

Mini FAQ

What part numbers does this replacement mention?

The listing names multiple part numbers, including 503280316 and 574331601, and also references 503280407, 503280304, 503280114, 503280313 and others.

Does the box include anything besides the carburetor?

Yes. It includes 5 gaskets, a spark plug, a spring, fuel line, 2 fuel filters and a shut-off valve.

Is this a universal carburettor?

Not based on the information provided. The listing points to specific Husqvarna models and Tillotson HS-series carburettor applications, and it advises checking images and dimensions for compatibility.

Do I need to change the air filter too?

The listing mentions air filter compatibility for certain Husqvarna part numbers, but it doesn’t say you must replace it. If you’re already in there, it’s worth inspecting your current filter and deciding based on condition.

Is it worth it?

A solid pick if you’ve identified that your compatible Husqvarna/Tillotson carburettor needs replacing, and you’re willing to verify images and dimensions before ordering—especially since the kit includes gaskets, filters, fuel line and a few supporting items. You may want to skip it if your symptoms point to something other than carburetion, or if you can’t confidently match your saw’s existing part numbers and fit details.
