If your snow blower won’t start, don’t panic. There are several straightforward steps you can take to diagnose and fix the problem. Start by checking the fuel, spark plug, and other key components to ensure everything is in working order.
Why Won’t My Snow Blower Start?
When a snow blower won’t start, it could be due to a few common issues. These include:
- Old or Bad Fuel: Fuel left in the tank from the previous season can degrade and cause starting issues.
- Faulty Spark Plug: A dirty or damaged spark plug can prevent the engine from igniting.
- Clogged Carburetor: Fuel residue can clog the carburetor, hindering fuel flow.
- Dead Battery: For electric start models, a dead battery can be the culprit.
How to Fix Common Snow Blower Starting Problems
1. Check the Fuel System
Old or contaminated fuel is a frequent cause of starting issues. Here’s what to do:
- Drain Old Fuel: If the fuel is older than 30 days, drain it and replace it with fresh gasoline.
- Add Fuel Stabilizer: This prevents the fuel from degrading over time.
- Inspect Fuel Cap: Ensure the fuel cap is venting properly to avoid vapor lock.
2. Inspect the Spark Plug
A spark plug that’s dirty or damaged can prevent your snow blower from starting.
- Remove the Spark Plug: Use a spark plug wrench to take it out.
- Clean or Replace: If it’s dirty, clean it with a wire brush. If damaged, replace it.
- Check the Gap: Ensure the spark plug gap is set to the manufacturer’s specifications.
3. Clean the Carburetor
A clogged carburetor can block fuel flow, preventing the engine from starting.
- Use Carburetor Cleaner: Spray carburetor cleaner into the carburetor to remove any residue.
- Rebuild or Replace: If cleaning doesn’t help, consider rebuilding or replacing the carburetor.
4. Test the Battery
For electric start snow blowers, a functional battery is essential.
- Charge the Battery: Use a battery charger to ensure it’s fully charged.
- Test Voltage: Use a multimeter to check the battery voltage. Replace if necessary.
Additional Troubleshooting Tips
- Check the Oil Level: Low oil levels can trigger safety features that prevent starting.
- Inspect the Safety Key: Ensure the safety key is inserted properly.
- Verify the Choke Position: Make sure the choke is in the correct position for starting.

How Often Should I Change the Oil in My Snow Blower?
It’s recommended to change the oil after the first five hours of use and then every 50 hours or once per season. Regular oil changes help maintain engine performance and longevity.
What Type of Fuel Should I Use in My Snow Blower?
Use fresh, unleaded gasoline with an octane rating of 87 or higher. Avoid using gasoline with more than 10% ethanol, as it can damage the engine.
How Do I Store My Snow Blower for the Off-Season?
Before storing, drain the fuel tank and run the engine until it stops. Clean the snow blower, check for any needed repairs, and store it in a dry, sheltered location.
Can I Use a Snow Blower on Wet Snow?
Yes, but wet snow can be more challenging to clear. Use a lower gear and work slowly to prevent clogging. Ensure the chute is clear before starting.
What Maintenance Should I Perform Before the Winter Season?
Before winter, perform a thorough inspection: check the spark plug, change the oil, inspect belts and augers, and ensure all moving parts are lubricated.
