If your Ariens snowblower won’t start, common issues include a dirty or damaged spark plug, old or contaminated fuel, a clogged carburetor, or a faulty electric starter. To fix these problems, clean or replace the spark plug, drain and refill the fuel tank with fresh fuel, clean or replace the carburetor, and check the wiring connections and starter motor. Additionally, ensure proper choke and throttle settings, clean or replace the fuel cap, replace broken shear pins, and recharge or replace the battery for electric start models.
Introduction
Struggling to start your Ariens snowblower when you need it most can be frustrating. In this article, we’ll explore the common reasons why your snowblower might not start in great detail and provide step-by-step solutions to help you fix it yourself. So, let’s get your snowblower back in action!
Why Your Ariens Snowblower Won’t Start
Check the Spark Plug
A dirty or damaged spark plug can prevent your snowblower from starting. The spark plug ignites the fuel-air mixture in the engine’s combustion chamber, creating the necessary power to run the snowblower. Over time, carbon deposits can build up on the spark plug’s electrode, decreasing its ability to create a spark. A worn or damaged electrode can also cause a weak or no spark, leading to starting problems.
How to fix:
- Locate the spark plug and remove the spark plug wire.
- Using a spark plug wrench, remove the spark plug.
- Inspect the spark plug for signs of wear, damage, or carbon buildup.
- If necessary, clean the spark plug with a wire brush and adjust the gap according to your owner’s manual.
- If the spark plug is beyond repair, replace it with a new one.
- Reinstall the cleaned or new spark plug and reconnect the spark plug wire.
Examine the Fuel System
Old or contaminated fuel can cause starting problems. Over time, fuel can degrade and lose its combustibility, making it difficult for the engine to start. Water or debris in the fuel system can also lead to poor engine performance and starting issues.
How to fix:
- Check the fuel level in your snowblower’s tank.
- If the fuel is old or contaminated, drain the tank.
- Refill the tank with fresh fuel, preferably with a fuel stabilizer to extend the fuel’s shelf life.
- Check the fuel lines for cracks or leaks and replace them if necessary.
- Replace the fuel filter if it’s clogged or damaged.
Inspect the Carburetor
A clogged or malfunctioning carburetor can prevent your snowblower from starting. The carburetor is responsible for mixing the right amount of fuel and air for combustion. Over time, dirt, debris, and fuel deposits can clog the carburetor’s jets, making it difficult for the engine to start and run smoothly.
How to fix:
- Turn off the fuel valve and remove the carburetor from the engine.
- Disassemble the carburetor and clean all the components with carburetor cleaner.
- Use a thin wire or a needle to clear any clogs in the jets.
- Reassemble the carburetor and reinstall it on the engine.
- Turn on the fuel valve and test the snowblower for proper operation.
Assess the Electric Starter
If your Ariens snowblower has an electric starter, a faulty wiring or a broken motor can cause the snowblower to not start. The electric starter uses a small motor to turn the engine’s crankshaft, initiating the combustion process.
How to fix:
- Check the wiring connections between the starter and the battery or power source, ensuring they are clean and secure.
- Use a multimeter to test the electric starter for proper voltage and continuity.
- If the electric starter is not functioning correctly, replace it with a new one.
Choke and Throttle Settings
Incorrect choke and throttle settings can make it difficult for your snowblower to start, especially in cold weather. The choke controls the amount of air entering the engine, while the throttle controls the engine speed.
How to fix:
- Set the choke to the “full” or “closed” position when starting a cold engine.
- Adjust the throttle to a medium or high setting for starting.
- Once the engine starts and warms up, gradually move the choke to the “open” position.
Clogged or Damaged Fuel Cap
A clogged or damaged fuel cap can prevent proper air flow into the fuel tank, causing a vacuum to form, which may hinder fuel flow to the carburetor.
How to fix:
- Inspect the fuel cap for any signs of damage or clogs.
- Clean the vent holes in the fuel cap using a small brush or a toothpick.
- If the fuel cap is damaged or cannot be cleaned, replace it with a new one.
Shear Pins
Shear pins are designed to break if the auger encounters a solid object, protecting the gearbox and other components from damage. However, a broken shear pin can prevent the auger from turning, making it seem like the snowblower won’t start.
How to fix:
- Inspect the shear pins on the auger shaft for signs of breakage.
- If any shear pins are broken, replace them with new ones according to the manufacturer’s specifications.
Dead Battery (For Electric Start Models)
If your Ariens snowblower has an electric start and the battery is dead, it won’t be able to start the engine.
How to fix:
- Check the battery voltage with a multimeter.
- If the battery is dead or low, recharge it according to the manufacturer’s instructions.
- If the battery cannot hold a charge, replace it with a new one.
| Issue | Cause | Fix |
|---|---|---|
| 1. Spark Plug | Dirty or damaged spark plug | Clean or replace the spark plug |
| 2. Fuel System | Old or contaminated fuel, clogged fuel filter, or damaged fuel lines | Drain and refill the fuel tank with fresh fuel, replace the fuel filter, and inspect fuel lines |
| 3. Carburetor | Clogged or malfunctioning carburetor | Clean or replace the carburetor |
| 4. Electric Starter | Faulty wiring or broken motor (for electric start models) | Check wiring connections, test the starter with a multimeter, and replace if necessary |
| 5. Choke and Throttle Settings | Incorrect settings, especially in cold weather | Adjust the choke and throttle settings according to the manufacturer’s guidelines |
| 6. Fuel Cap | Clogged or damaged fuel cap | Clean the vent holes or replace the fuel cap |
| 7. Shear Pins | Broken shear pins on the auger shaft | Replace broken shear pins with new ones |
| 8. Dead Battery | Dead or low battery (for electric start models) | Recharge or replace the battery |

Preventative Maintenance Tips
To prevent future issues with your Ariens snowblower, follow these maintenance tips:
- Regularly Change the Engine Oil: Changing the engine oil at least once per season will keep your snowblower running smoothly. Consult your owner’s manual for the recommended oil type and change frequency.
- Inspect and Replace Belts: Regularly inspect the belts for wear and tear, and replace them as needed. Frayed or loose belts can cause performance issues and even lead to more severe problems if left unaddressed.
- Keep the Snowblower Clean: After each use, clear any snow or ice buildup from the auger, chute, and other components. This helps prevent rust, corrosion, and blockages that can impact performance and cause starting issues.
- Store the Snowblower Properly: When not in use, store your snowblower in a dry, cool place to protect it from the elements and reduce the chances of rust and corrosion.
- Perform Regular Inspections: Before each use, check the spark plug, fuel system, carburetor, and electric starter for any signs of wear, damage, or clogs. Addressing issues early can help prevent more significant problems down the line.
By following these preventative maintenance tips and addressing potential issues as they arise, you can ensure your Ariens snowblower remains reliable and ready to tackle even the toughest winter conditions. Stay safe and enjoy a clear, snow-free driveway all season long!
