Simplicity 555 Snowblower Won’t Start? Your Ultimate Fix-It Guide
Winter arrives with a blanket of serene white, but that beauty quickly becomes a back-breaking problem when it blocks your driveway. You reach for your trusted Simplicity 555 snowblower, a machine known for its robust build, but instead of a roar, you get a sputter, or worse, silence. A non-starting snowblower is a common frustration that leaves you stranded with a shovel in hand, facing hours of manual labor.
This situation is more than an inconvenience; it’s a race against time before the snow compacts into ice. The core of the problem often lies hidden within the fuel system, ignition, or drive mechanism. Understanding the root cause is the first step to reclaiming your winter freedom.

Unlocking the Power of Your Simplicity 555: A Legacy Machine
The Simplicity 555 isn’t just another snowblower; it’s a testament to an era of heavy-duty manufacturing. These machines were built with thick steel augers and housings, designed to outlast seasons of punishing use. Unlike many modern machines, the 555 boasts a level of durability that makes it a prime candidate for restoration and reliable use, provided you understand its quirks.
The challenge with these vintage powerhouses is that they require a different level of care. Modern ethanol-blended fuels can wreak havoc on their older carburetor designs, and years of vibration can lead to specific, predictable mechanical issues. Knowing how to address these common failure points is key to keeping your 555 in top fighting form.
Core Specifications of the Simplicity 555
Understanding the fundamental design of your machine is crucial for troubleshooting and sourcing parts. While variations exist, the classic Simplicity 555 model generally adheres to these specifications.
| Feature | Specification |
|---|---|
| Engine | Typically a 5 HP Tecumseh Snow King |
| Clearing Width | 22 inches |
| Drive System | Friction Disc Drive |
| Speeds | Multiple forward and reverse speeds (often 5 forward, 2 reverse) |
| Construction | All-steel auger and housing |
| Starting System | Manual Recoil (Electric start optional on some models) |
The Ultimate Troubleshooting Guide: From Silence to Snow-Slinging Power
When your Simplicity 555 refuses to start or run properly, the issue can almost always be traced back to three critical areas: fuel, spark, or compression. We will systematically diagnose and solve the most common problems you’ll encounter, turning you into a confident DIY repair expert.
Problem 1: The Engine Won’t Start
This is the most frequent complaint. You pull the cord, but nothing happens. The culprit is very often old or contaminated fuel left over from the previous season.
The Fuel System Fix: Modern gasoline can go bad in as little as 30 days, leaving behind a gummy varnish that clogs the tiny passages in the carburetor. Draining old fuel is not enough; the carburetor must be thoroughly cleaned.
- Safety First: Disconnect the spark plug wire to prevent any chance of an accidental start.
- Drain the Tank: Empty all old gasoline from the fuel tank into an approved container.
- Access the Carburetor: You may need to remove a protective shroud or cover to get clear access to the carburetor.
- Clean the Bowl: Loosen the nut on the bottom of the carburetor bowl. Varnish and water often collect here. Thoroughly clean the inside of the bowl and the nut with carburetor cleaner and a wire brush.
- Clear the Jets: The main jet (often part of the bowl nut) and pilot jets have minuscule holes that get clogged. Use a very thin wire or a specialized jet cleaning tool to gently clear these passages. Never force a tool through the jet, as this can damage it.
A pristine carburetor is the heart of a well-running engine. This single maintenance step solves the majority of starting problems and is a non-negotiable part of annual servicing.
Problem 2: The Engine Sputters and Stalls
If the engine starts but runs rough or dies under load, you likely have a fuel delivery issue or a weak spark. After cleaning the carburetor, the next step is to verify the ignition system.
The Spark Test: A strong, blue spark is essential for igniting the fuel mixture. A weak, orange spark won’t be reliable.
- Check the Spark Plug: Remove the spark plug and inspect it. If it’s covered in black soot or wet with oil, it needs to be replaced. Ensure the gap is set to the manufacturer’s specification (usually found in the manual).
- Test for Spark: With the plug removed, re-connect it to the spark plug wire. Hold the threaded base of the plug firmly against a metal part of the engine block. Pull the starter cord and look for a bright blue spark across the electrode. If there’s no spark or it’s weak, the ignition coil may be failing.
Problem 3: The Wheels Won’t Turn (But the Engine Runs)
This is a classic mechanical failure, and on the Simplicity 555, the problem almost always points to the friction disc drive system. This system uses a rubber-edged wheel (the friction disc) that presses against a spinning metal plate to transfer power to the wheels.
The Friction Disc Solution: Over time, the rubber on the friction disc wears down, gets glazed with oil, or cracks. When this happens, it can no longer grip the drive plate effectively, and the wheels won’t turn, especially under load.
- Access the Drive: Tip the snowblower forward to rest on its auger housing. You will need to remove the bottom cover plate located between the wheels to access the drive system.
- Inspect the Disc: Look at the rubber wheel. If the rubber is worn down to less than 1/8 inch, is cracked, or looks shiny and glazed, it must be replaced. This is a common wear item.
- Replacement: The process involves removing the hex shaft that the friction disc rides on. This can be an intricate job, but it is entirely manageable with basic hand tools. Be sure to clean the metal drive plate with brake cleaner to remove any oil or grease residue for a good grip.
Advanced Maintenance for Unstoppable Performance
Going beyond basic repairs will ensure your Simplicity 555 operates at peak efficiency for years to come. These steps separate the casual user from the proactive owner whose machine starts on the first pull, every time.
Shear Pin Savvy: More Than Just a Bolt
Shear pins are designed to break, protecting the expensive auger gearbox if the augers hit a rock or a thick chunk of ice. Never replace a shear pin with a standard bolt. A regular bolt is too strong and will not break, transferring the damaging force directly to the gearbox, which can lead to a catastrophic and costly failure. Understanding the difference between various pin types, much like the debate over duracore vs solid core materials in other applications, highlights how specialized components are vital for safety and longevity.
Optimizing Your Toolkit
Maintenance is far easier with the right tools. A cordless impact driver can make tasks like replacing the friction disc or skid shoes much faster. Investing in a reliable power source, even considering options like the best knock off dewalt batteries, can modernize your repair routine and save significant time and effort.
Is the Simplicity 555 Still a Contender?
In a world of modern, feature-rich snowblowers, does this vintage machine still have a place? The answer is a resounding yes, for the right owner. It lacks the power steering and heated handgrips of premium models, but its raw durability is hard to match. When considering a new purchase, a simplicity vs ariens snowblower comparison often comes down to this trade-off: modern convenience versus old-school reliability and build quality.
The Simplicity 555 is for the owner who appreciates mechanical simplicity and is willing to perform routine maintenance. Its all-steel construction means it can handle tough, icy conditions that might damage lighter-duty machines. Sourcing parts is still relatively easy through online suppliers and dedicated dealers, ensuring this workhorse can be kept in service for decades to come.
Final Verdict: The Enduring Value of the Simplicity 555
The Simplicity 555 snowblower represents a smart investment for those who value longevity and repairability over flashy features. Its common problems are well-documented and easily solvable with basic mechanical knowledge. By mastering the fuel system, monitoring the ignition, and maintaining the friction disc drive, you can ensure this powerful machine is always ready to tackle the worst of winter.
Don’t let a simple, fixable issue leave you out in the cold. With this guide, you have the knowledge and confidence to keep your Simplicity 555 running like the day it was made, clearing snow efficiently and reliably season after season.
