There's nothing worse than waking up to fresh snow, bundling up, pulling the starter cord on your snow blower, and hearing nothing. A snow blower that won’t start can be a common headache for homeowners throughout Connecticut; some don't even prepare until that first big storm hits. The good news is, most of the time, the fix is pretty simple.
Whether it's a fuel problem, a spark plug, or something more minor, here are the most common reasons your snow blower won't start and how to get it running again before the snow piles up.
5 Common Causes Why a Snow Blower Won’t Start
1. Old or Stale Fuel
Getting a snow blower that refuses to start is one of the most common issues that owners experience, with poor gas quality topping the list of reasons. Gas that is left sitting in a snowblower carbureted engine for months, particularly during summer, will eventually break down into varnish that can clog a carbureted fuel system.
Easy Fix:
- Drain the old fuel and fill it with fresh gasoline.
- Add a fuel stabilizer at the end of each season to prevent gumming.
- Use the correct octane and ethanol blend recommended by your manufacturer.
2. Faulty or dirty spark plug
It is possible that new fuel is not igniting in the engine. Inspect the spark plug in this situation. A spark plug that is fouled, wet, or cracked can cause the engine not to ignite.
Easy Fix:
- Remove the plug and check it for carbon buildup or corrosion.
- Make sure that the wire is securely fastened.
- Replace the plug if it's damaged or looks worn.
3. Carburetor Problems or Airflow Blockages
Your carburetor is what mixes the air and fuel to burn, and that’s where a small clog could keep the engine from starting. Generally, varnish is what clogs the jets in a carburetor.
Easy Fix:
- Replace the air filter if it is dirty.
- Apply carburetor cleaner to loosen any residue in the bowl or jets.
- Ensure that the choke and throttle are in the correct starting position.
4. Fuel Flow or Safety Switch Issues
Often, the problem is not a problem of mechanics, but of a switch in the wrong place, a valve in the wrong position.
Easy Fix:
- Begin by making sure that the fuel shut-off valve is turned ON.
- Ensure the ignition key or safety interlock is in place.
- Before pulling the cord, the throttle needs to be set at “fast” or “run.”
5. Poor Off-Season Storage or Lack of Maintenance
If your snow blower has been sitting since last winter, storage conditions might be at fault. Old fuel, moisture, or even rodent nests can interfere with startup.
Easy Fix:
- Drain fuel at the end of the season or use a stabilizer before storage.
- Start the blower at least once before the first snowfall every year.
- Keep it covered, clean, and store it in a dry place.
