If your Ariens snowblower won’t start, you’re not alone. Many homeowners face this problem, especially after the first big snowfall. You rely on your snowblower to clear driveways and paths quickly, so a machine that won’t start can be frustrating. The good news is, most starting issues are easy to fix with a little know-how. This guide will walk you through common reasons, practical troubleshooting steps, and how to avoid future problems. Whether you’re new to snowblowers or have used them for years, you’ll find clear advice that helps you get your Ariens running again.
Common Reasons Your Ariens Snowblower Won’t Start
Before grabbing tools or calling for help, it’s smart to understand the main causes. Many issues come from simple mistakes or overlooked maintenance.
1. Old Or Bad Fuel
Gasoline can go bad in just 30 days. If your snowblower sat unused all summer, the fuel may have degraded, making it hard to start.
2. Spark Plug Problems
A dirty or damaged spark plug prevents the engine from igniting fuel. Even a small crack or buildup can cause trouble.
3. Clogged Fuel System
The carburetor and fuel lines can get clogged by old gas, dirt, or moisture. If fuel can’t reach the engine, your snowblower won’t start.
4. Dead Battery (electric Start Models)
If your Ariens has an electric start, a weak or dead battery will make starting impossible.
5. Primer Bulb Issues
The primer bulb pumps fuel into the carburetor for easier starting. If it’s cracked or not working, your machine might not get enough fuel.
6. Choke Or Throttle Mistakes
Incorrect settings for choke or throttle can prevent starting. Many beginners forget to use full choke when starting cold.
7. Blocked Air Filter
A dirty or blocked air filter restricts airflow, affecting engine performance.
8. Safety Switches Or Key Not Inserted
Some Ariens models have safety switches or require a key. If these aren’t set correctly, the engine won’t start.
Quick Troubleshooting Steps
Let’s walk through practical steps to find and fix the problem. Most issues don’t need special tools—just patience and careful checking.
Step 1: Check The Fuel
- Make sure there’s enough fresh gasoline in the tank.
- If the fuel is old, drain it and refill with new gas.
- For best results, use ethanol-free fuel or add a stabilizer. Ethanol can attract moisture and cause clogs.
Step 2: Inspect The Spark Plug
- Remove the plug and look for dirt, cracks, or corrosion.
- Clean with a wire brush or replace if it looks damaged.
- Make sure the spark plug gap matches your Ariens manual (usually 0.020–0.030 inches).
Step 3: Review Choke And Throttle Settings
- Set the choke to FULL for a cold start.
- Move the throttle to FAST or RUN.
- After starting, gradually move the choke to OFF.
Step 4: Prime The Engine
- Press the primer bulb 3–5 times. If it feels cracked or doesn’t push fuel, replace it.
Step 5: Check Battery And Electric Start
- For electric start models, plug into an outlet and try again.
- If the battery is dead, recharge or replace it.
Step 6: Examine Safety Features
- Make sure the safety key is inserted and switches are set to ON.
- Some models have a handle safety lever—squeeze it tightly while starting.
Detailed Fixes For Common Problems
Sometimes quick checks aren’t enough. Let’s dig deeper into the most frequent issues and how to solve them.
Fuel System Cleaning
A clogged fuel system is a top reason snowblowers don’t start. Here’s how to clean it:
1. Drain Old Gas:
Use a siphon or drain plug. Dispose of fuel safely.
2. Clean Carburetor:
Remove and spray with carb cleaner. If you’re comfortable, disassemble and clean inside.
3. Check Fuel Lines:
Look for cracks or blockages. Replace if needed.
4. Install New Fuel Filter:
Many Ariens models have a filter on the fuel line—swap it for a new one.
Fuel System Comparison Table
Here’s a quick look at symptoms and solutions for fuel system issues:
| Issue | Possible Cause | Solution |
|---|---|---|
| Engine sputters | Dirty carburetor | Clean carburetor with spray |
| No start | Old fuel | Drain and refill |
| Weak start | Blocked fuel filter | Replace filter |
Spark Plug Replacement
Ariens snowblowers use standard spark plugs, but getting the right fit matters. Check your model’s manual for type and gap.
- Remove old plug with a wrench.
- Clean or replace as needed.
- Reinstall and tighten, but don’t overtighten.
Spark Plug Performance Table
See how plug condition affects starting:
| Spark Plug Condition | Engine Starting | Action Needed |
|---|---|---|
| Clean, correct gap | Easy start | No action |
| Dirty, wrong gap | Hard start | Clean and adjust gap |
| Cracked or corroded | No start | Replace plug |
Battery And Electric Start Fixes
If your Ariens snowblower has electric start, battery health is key.
- Test battery with a multimeter; aim for 12.6V or higher.
- Recharge if voltage is low.
- Replace after 2–3 years, especially if it’s not holding charge.
Air Filter Maintenance
Dirty air filters stop your snowblower from starting or running well. Ariens recommends checking the filter every season.
- Remove filter cover.
- Clean with compressed air or replace if dirty.
- Make sure filter fits snugly.
Safety Switches And Keys
Modern Ariens snowblowers include safety features. If your machine won’t start, double-check:
- Key is in place.
- Handle safety lever is squeezed.
- All switches are set to ON.
Preventive Maintenance Tips
Preventing starting issues saves time and money. Here are practical tips to keep your Ariens snowblower ready for winter.
1. Use Fresh Fuel:
Always use fresh gas and add a stabilizer if storing the machine.
2. Check Oil Level:
Low or dirty oil harms the engine. Change oil every season or after 25 hours of use.
3. Store Properly:
Keep your snowblower in a dry area. Cover to protect from moisture.
4. Inspect Before Each Use:
Check fuel, oil, spark plug, and air filter before starting.
5. Run The Engine Occasionally:
Start your snowblower once a month, even in summer, to keep parts moving.

Non-obvious Insights For Beginners
Many first-time snowblower owners miss these points:
- Ethanol in gas attracts water, causing carburetor clogs. Using ethanol-free fuel can prevent many issues.
- Priming too much floods the engine. If the snowblower smells strongly of gas, wait 10–15 minutes before trying again.
- Cold weather affects batteries. Store the battery indoors if possible, and warm it up before starting.

| Deluxe 28 | Pull & Electric | Old fuel |
| Compact 20 | Pull start | Spark plug dirty |
| Professional 32 | Electric only | Safety switch not engaged |
This shows that while all Ariens snowblowers are reliable, each model has its own quirks. Check your manual for specific advice.

Frequently Asked Questions
What Fuel Should I Use In My Ariens Snowblower?
Ariens recommends using regular unleaded gasoline with no more than 10% ethanol. For best performance, use ethanol-free fuel and add a stabilizer if storing your snowblower. Avoid old gas—it can cause starting problems and clog the carburetor.
How Often Should I Replace The Spark Plug?
Change the spark plug every season or after 25–30 hours of use. If your snowblower won’t start, check the plug for dirt or damage. A clean, properly gapped plug makes starting easier and improves performance.
My Snowblower Smells Like Gas But Won’t Start. What Should I Do?
This usually means the engine is flooded from too much priming or choke. Wait 10–15 minutes to let extra gas evaporate, then try starting again with less choke and fewer primer presses. If it still won’t start, check the spark plug and air filter.
Can I Use An Extension Cord For Electric Start?
Yes, but always use a heavy-duty extension cord rated for outdoor use. Plug into a grounded outlet. Using the wrong cord can reduce power and damage the starter. Check your Ariens manual for cord length and gauge advice.
