Step 1: Check the Fuel

Old or bad fuel is one of the most common reasons snow blowers won’t start. Here’s what to do:

  • Inspect the fuel tank. If the fuel has been sitting for more than 30 days, it may have degraded. Drain the old fuel and replace it with fresh, ethanol-free fuel.
  • Use a fuel stabilizer to prevent fuel from breaking down and clogging the carburetor.
  • Prime the engine. If your snow blower has a primer bulb, press it a few times to get fuel into the carburetor.

Pro Tip: Always use fresh fuel at the start of the season to avoid issues.

Step 2: Check the Spark Plug

A dirty or damaged spark plug can prevent your snow blower from starting. Here’s how to check it:

  • Remove the spark plug using a spark plug wrench.
  • Inspect it for cracks, carbon buildup, or wear. If it’s dirty, clean it with a wire brush. If it’s damaged, replace it.
  • Test the spark by reattaching the spark plug wire and holding the plug against the engine block. Pull the starter cord and look for a spark. If there’s no spark, replace the plug.

Neighborly Advice: Keep a spare spark plug handy—it’s an inexpensive fix that can save you time.

Step 3: Check the Carburetor

The carburetor mixes fuel and air for the engine. If it’s clogged, your snow blower won’t start.

  • Inspect for clogs by removing the carburetor and checking for dirt or debris. Clean it with a carburetor cleaner spray.
  • Adjust the settings if the carburetor is clean but the engine still won’t start. Check the owner’s manual for instructions on adjusting the air-fuel mixture.

DIY Tip: If you’re not comfortable cleaning the carburetor, a local technician can help.

Step 4: Inspect the Fuel Lines and Filter

Fuel lines and filters can become clogged over time, preventing fuel from reaching the engine.

  • Check the fuel lines for cracks, leaks, or blockages. Replace damaged lines.
  • Clean or replace the fuel filter if it’s clogged. A clean filter ensures proper fuel flow.

Step 5: Check the Choke and Throttle

The choke and throttle settings play a big role in starting your snow blower.

  • Set the choke to the fully closed position for a cold start.
  • Adjust the throttle to the “high” or “fast” position before pulling the starter cord.

Step 6: Inspect the Starter System

If your snow blower has an electric starter:

  • Check the power cord to ensure it’s securely connected and not damaged.
  • Test the starter button. If it doesn’t engage, the starter may need to be replaced.

For manual starters:

  • Inspect the recoil mechanism. If the pull cord doesn’t retract smoothly, the recoil system may need repair.

Step 7: Look for Other Issues

If none of the above steps work, there may be a deeper issue:

  • Compression problems. If the engine lacks compression, it may need professional repair.
  • Shear pin damage. If the auger isn’t turning, check the shear pins and replace them if they’re broken.
