Hipa Rancher Tune-Up Kit for Husqvarna 50/51/55 — Carburetor, Ignition Coil & Air Filter

Hipa 55 51 Rancher Tune-Up Kit is a complete replacement set containing a carburetor, ignition coil, air filter, fuel parts and spark plug to restore starting and running on Husqvarna Rancher 50/51/55 chainsaws.

If your Husqvarna Rancher saw is hard to start, runs unevenly, or leaks fuel, replacing worn ignition, fuel and air components often fixes the problem faster and cheaper than a full service. This Hipa kit groups the compatible carburetor (WT-170-1 / 503281504), ignition coil (replaces Husq# 544018401 and related numbers), air filter (503608301) and essentials into one rebuild package designed for 50/51/55 Rancher model years listed in the compatibility notes.

What parts come in the Hipa Rancher 55/51 rebuild kit and why they matter?

The kit includes a complete carburetor assembly, ignition coil, replacement air filter, fuel filter, fuel line, carburetor gasket and a spark plug. Each component targets a common failure point: the carburetor meters fuel/air, the coil provides a strong spark, and the filter keeps debris out of the engine.

• Carburetor WT-170-1 / 503281504 — restores correct fuel metering and idling.
• Ignition coil (fits Husq# variants like 544018401) — improves spark reliability for consistent starts.
• Air filter 503608301 — protects the engine from dust and sawdust ingestion.
• Fuel filter, line, gasket, spark plug — ensure clean fuel delivery and correct sealing.

Which Husqvarna Rancher models and years are compatible with this kit?

Hipa specifies fitment for many Rancher 50, 51 and 55 chainsaws from the early 1990s through mid-1990s. Check the model and production dates stamped on your saw to confirm compatibility before ordering.

• Fits: Rancher 55 and 51 models in several production ranges (1990–1994 variants listed).
• Compatible parts referenced: WT-170, 503281504 carburetors and ignition coil numbers including 544018401.
• Note: Not compatible with Rancher 55 (1991-10) model number 505316751 — verify your serial/model tag.

How does installing this kit affect saw performance and maintenance?

Installing these parts typically improves cold-start behavior, steadier idling, consistent throttle response, and reduces misfires caused by weak spark or clogged filters. It also reduces the need for interim troubleshooting by replacing multiple wear items at once.

• Better starting due to a new ignition coil and fresh spark plug.
• Smoother running with a rebuilt carburetor and new fuel filter/line.
• Longer engine life and fewer clogs thanks to a new air filter.

Who is this kit for? If you own a Husqvarna Rancher 50, 51 or 55 chainsaw from the compatible year ranges and are experiencing hard starting, rough idle, fuel leaks, or weak throttle response, this Hipa rebuild kit provides a cost-effective way to return the saw to reliable operation without buying OEM parts separately. It's suited for homeowners, landscape professionals, and small saw repair shops comfortable performing basic carburetor and ignition swaps. Always verify your model number and consult a service manual or technician if you are unsure about installation steps or safety procedures.
