You might be tempted to push it to the curb, frustrated by starting issues or lackluster performance. Before you give up on this classic machine, understand that you are holding a piece of peak engineering, a snowblower built with a quality that is rarely seen today.

The problem isn’t the machine; it’s that decades of neglect have hidden its true potential. This guide will show you how to resurrect your aging HS55, transforming it from a frustrating piece of junk into a reliable, snow-devouring beast that can outperform many modern, plastic-clad alternatives.

Why the Honda HS55 is a Classic Worth Keeping

In an age of disposable products, the Honda HS55 stands out as a testament to durability. Manufactured primarily in the 1980s, these machines were built during a golden era for Honda, when products were designed to last a lifetime, not just a few seasons. Understanding its inherent value is the first step toward appreciating what you have.

Unmatched Durability: The Golden Era of Honda Engineering

The core of the HS55’s legendary status is its construction. Unlike many contemporary snowblowers that rely heavily on plastic components, the HS55 features a robust, all-metal build. From the heavy-gauge steel of the auger housing to the solid transmission components, this machine was engineered for brutal winters and decades of use.

Its powerful and efficient Honda 4-stroke engine is a marvel of simplicity and reliability. These engines were designed to be maintained and rebuilt, not replaced, making them a favorite among homeowners and small-engine enthusiasts. The simple, mechanical design ensures that with basic care, it will continue to function flawlessly for years to come.

Simplicity and Repairability

Modern snowblowers often come with complex electronic systems and proprietary parts that make DIY repairs nearly impossible. The HS55, in contrast, is a purely mechanical machine. Its straightforward design allows owners with basic mechanical skills to perform most maintenance and repairs themselves.

This repairability is a significant advantage. Instead of facing costly dealer repairs for a complex electronic issue, you can often solve problems on an HS55 with standard tools and readily available parts. This simplicity not only saves money but also empowers you to keep your equipment in peak condition.

The Hidden Power in an Old Frame

Despite its age and modest 5.5 horsepower engine, a well-tuned HS55 can deliver astonishing performance. Its two-stage design, featuring a steel auger to break up snow and a high-speed impeller to throw it, is highly effective for clearing even heavy, wet snow. Many users report that their vintage HS55 can outperform newer, higher-horsepower machines.

The challenge lies in unlocking this dormant power. After years of sitting with old fuel in the tank or worn-out belts, the machine’s performance degrades. The key is to address these common points of failure to restore its original, formidable capabilities.

The Ultimate HS55 Troubleshooting Guide: From Nuisance to Non-Starter

Over the years, any machine will develop common issues. For the HS55, these problems are almost always predictable and fixable. By systematically addressing these pain points, you can solve the vast majority of performance problems.

Problem 1: The Engine Won’t Start or Sputters

The number one cause of starting problems in any small engine is the fuel system. Old gasoline degrades, turning into a varnish-like substance that clogs the tiny passages in the carburetor. An engine that requires the choke to be partially on to run smoothly is a classic symptom of a clogged main jet.

Start by completely draining the old fuel from the tank and carburetor bowl. Refill with fresh, high-octane gasoline. If the problem persists, the carburetor needs a thorough cleaning. You must remove the carburetor, disassemble it, and clean the jets and passages with carburetor cleaner and compressed air. Be meticulous; even a tiny piece of debris can cause issues.

Problem 2: The Auger or Impeller Won’t Engage

If the engine runs but the snow-throwing mechanism doesn’t work, the issue is likely mechanical. The most common culprit is a broken shear bolt. Shear bolts are safety features designed to break if the auger hits a large rock or chunk of ice, protecting the more expensive gearbox from damage.

Inspect the shear bolts on the auger shaft and replace any that are broken. If the bolts are intact, the problem may be a worn or improperly tensioned auger belt. You will need to remove the belt cover to inspect the condition of the belt and the function of the tensioner pulley.

Problem 3: Poor Throwing Distance

A common complaint with older two-stage snowblowers is a disappointing throwing distance. This can be caused by several factors. First, ensure the engine is running at its maximum governed RPM; low engine speed will result in weak performance. You can increase engine RPM for a significant power boost.

Another cause is a worn or slipping impeller belt. Over time, the gap between the impeller blades and the housing wall can increase due to wear, reducing efficiency. A popular and highly effective modification is to install an “impeller kit,” which consists of rubber flaps bolted to the impeller blades to close this gap, dramatically improving throwing distance and preventing clogs with wet snow.

Symptom	Likely Cause	Solution
Engine will not start.	Old/bad fuel, clogged carburetor, faulty spark plug.	Drain fuel, clean carburetor, replace spark plug.
Engine runs only with choke on.	Clogged main jet in carburetor.	Thoroughly clean carburetor jets and passages.
Auger does not spin.	Broken shear bolts or worn/broken auger belt.	Replace shear bolts, inspect and replace auger belt.
Snowblower does not move.	Worn or broken drive belt.	Inspect and replace the drive belt.
Poor snow throwing distance.	Low engine RPM, worn impeller belt, large impeller gap.	Adjust engine to full RPM, replace belt, consider an impeller kit.
Engine dies when auger is engaged.	Clogged carburetor or frozen/jammed auger assembly.	Clean carburetor; inspect auger for ice or obstructions.

Step-by-Step Annual Maintenance for Peak Performance

Consistent, preventative maintenance is the key to reliability. Performing these simple checks and services will ensure your HS55 starts on the first pull every winter and runs strong all season long.

Pre-Season Checklist: Your Winter Preparation Ritual

Before the first snowflake falls, dedicate an afternoon to preparing your machine. This single act will prevent 90% of winter frustrations. Start by changing the engine oil; SAE 5W-30 is recommended for general all-temperature use.

Next, replace the spark plug. A new plug is inexpensive and ensures a strong spark for easy starting. Finally, inspect both the auger and drive belts for cracks and wear, and check the tire pressure. Proper maintenance is foundational, much like you would want to fix a deteriorating door lock hole before the entire door frame fails.

In-Season Checks: Keeping it Reliable

During the winter season, a few quick checks can keep your HS55 running smoothly. Before each use, visually inspect the shear bolts to ensure they are intact. After use, if the snow was particularly wet, run the auger for a minute to clear out any remaining slush that could freeze and jam the mechanism.

Always use a fuel stabilizer if you anticipate the machine will sit for more than a few weeks between snowfalls. This prevents the fuel from gumming up the carburetor and causing problems mid-season.

Post-Season Storage: The Secret to an Easy Start Next Year

How you store your snowblower is the most critical factor for its longevity. At the end of the season, the fuel system must be properly prepared for storage. You can either drain the fuel tank and carburetor completely or fill the tank with fresh, stabilizer-treated fuel and run the engine for 10 minutes to circulate it through the system.

Clean the entire machine of dirt, salt, and grime to prevent rust. Lubricate all moving parts, such as the chute crank and pivot points. Store the snowblower in a dry, protected area to protect it from the elements, ensuring it’s ready to go when you need it next winter.

Sourcing Parts for a Vintage Machine: A Modern Challenge

One of the primary concerns with owning a vintage machine is parts availability. While many components for the HS55 are still available, finding the right ones requires a bit of research. Some critical parts like certain gearbox components may be obsolete, making it important to know where to look.

Identifying the Correct Part Numbers

The first step in sourcing parts is identifying the exact part number you need. Your machine’s serial number is crucial, as there were slight variations of the HS55 produced over the years. Online resources, including Honda’s official parts diagrams and third-party suppliers, offer detailed schematics that allow you to pinpoint the correct part number.

Having the correct number is essential when searching, as it eliminates guesswork and ensures compatibility. Take the time to find the diagram for your specific model to avoid purchasing the wrong component.

Where to Find HS55 Parts Today

While some parts may no longer be in production, a vibrant secondary market exists. Your local Honda dealer may still be able to order common maintenance items like belts and spark plugs. For more specific parts, online retailers are your best bet.

Websites specializing in OEM parts, as well as auction sites like eBay, are excellent sources for both new old stock (NOS) and used components. Online forums dedicated to snowblower enthusiasts can also be invaluable resources, with members often selling or trading parts from donor machines.

Is the HS55 Still a Good Buy Today?

For the right person, a used Honda HS55 can be an incredible value. However, it’s not the perfect machine for everyone. Weighing the advantages and disadvantages is crucial before making a purchase.

Weighing the Pros and Cons

The primary advantages are its legendary durability, low purchase price, and DIY-friendly nature. For a few hundred dollars, you can acquire a machine that, with some care, will outlast brand-new models that cost three or four times as much. It’s a workhorse built for serious snow removal.

The downsides are its age, the potential difficulty in finding certain parts, and the lack of modern conveniences. Most HS55 models do not have electric start, power steering, or heated handgrips. If you value these features over raw durability, a newer machine might be a better choice. Making an informed decision here is as important as checking the quality of a Genius screen door from Costco before installation to ensure it meets your needs.

What to Look for When Buying a Used HS55

When inspecting a used HS55, pay close attention to several key areas. Check the auger housing and impeller for signs of excessive rust or damage from hitting rocks. Look for oil leaks around the engine and transmission, as replacing seals can be a labor-intensive job.

Ask the owner to start it from cold to see how easily it fires up. Engage the drive and auger clutches to ensure they operate smoothly. A well-cared-for machine should run strong, but even a neglected one can be a great restoration project if the price is right.

Beyond the Basics: Advanced Tips and Modifications

For enthusiasts looking to maximize their HS55’s potential, several modifications and advanced techniques can elevate its performance to the next level. These tips are for those who want to turn their classic snowblower into an unbeatable winter tool.

The Impeller Modification for Superior Snow Throwing

As mentioned earlier, the single most effective performance upgrade is the impeller kit. By attaching durable rubber paddles to the impeller blades, you close the gap between the blade and the housing. This simple change dramatically increases the machine’s efficiency, allowing it to throw snow significantly farther and virtually eliminating the frustrating chute clogs that plague two-stage blowers in wet, heavy snow.

Carburetor Deep Dive: Beyond a Simple Cleaning

For a carburetor that is severely gummed up from years of old fuel, a simple spray cleaning may not be enough. In these cases, an ultrasonic cleaner can work wonders. This device uses high-frequency sound waves to dislodge stubborn varnish and deposits from even the smallest internal passages, restoring the carburetor to like-new condition.

Addressing Common Smoke Issues

It’s not uncommon for an older engine to produce a small puff of blue or white smoke upon startup, which typically burns off as the engine warms. However, persistent smoke can indicate underlying issues. This is a problem you’ll want to investigate, just as you would want to figure out how to stop smoke from going upstairs if you noticed a problem with your fireplace.
