Getting your snow blower ready after months in storage can feel stressful, especially when winter arrives quickly. Many people wait until the first snowstorm to check their machine, only to find it won’t start. This is a common problem, but it’s also easy to avoid if you know the right steps. Whether you own a single-stage, two-stage, or electric snow blower, starting it up after storage requires careful attention. This guide will walk you through everything you need to know, from checking fuel and oil to troubleshooting common issues. Following these steps can save you time, money, and frustration when the snow hits.
Why Snow Blowers Won’t Start After Storage
After months without use, snow blowers often have trouble starting. Several things can go wrong during storage:
- Old fuel can turn into varnish and clog the carburetor.
- Moisture may cause rust or corrosion in the engine.
- Battery can lose charge or fail if not maintained.
- Belts and cables might become stiff or brittle.
- Small animals sometimes nest inside machines, blocking airflow.
Understanding these problems helps you prepare for a quick and smooth start.
Safety First: Preparing To Start Your Snow Blower
Before you touch your snow blower, make sure you’re safe:
- Read the owner’s manual to know your specific model’s instructions.
- Move the blower outdoors or into a well-ventilated space.
- Disconnect spark plug wire (for gas blowers) before any inspection or repair.
- Wear gloves and safety glasses to protect your hands and eyes.
- Check for leaks of oil or fuel under the machine.
These steps prevent injuries and ensure you spot problems before they get worse.
Inspecting Your Snow Blower After Storage
A careful inspection is the first step to a successful start. Look for these key issues:
Check For Visible Damage
- Cracked or brittle rubber on belts and cables can cause failures.
- Loose bolts or nuts may indicate vibration damage.
- Rodent nests or chewed wires can create electrical problems.
Examine Fuel And Oil
Gasoline goes bad in as little as 30 days. If you left fuel in the tank, it’s likely old.
- Smell the fuel: Bad gas smells sour or like varnish.
- Check oil level: Low oil can damage the engine.
- Look for water: Water in fuel or oil appears cloudy or separates.
Inspect The Auger And Impeller
- Turn the auger by hand (with the machine off) to check for resistance.
- Remove any debris stuck in the housing.
- Check shear pins for damage or wear.
Examine The Battery (if Electric Start)
- Test the battery voltage with a multimeter (should be at least 12.4V for most models).
- Look for corrosion on terminals.
Fuel System: Key To Easy Starting
The fuel system is the most common source of starting problems after storage. Here’s how to make sure yours is ready.
Remove Old Fuel
Old fuel can clog the carburetor and fuel lines. Always drain it if you didn’t use a stabilizer last season.
- Siphon out old gas from the tank.
- Dispose of gasoline at a recycling center—never pour it down the drain.
- Clean the fuel tank with a rag if possible.
Add Fresh Fuel
Use only fresh gasoline (less than 30 days old). Choose the right octane as recommended by your snow blower manual.
- For most blowers: 87 octane, E10 or less ethanol
- For 2-cycle engines: Correct oil mix ratio
Adding a fuel stabilizer helps prevent problems during the next storage.
Clean Or Replace Fuel Filter
A dirty fuel filter restricts flow and makes starting difficult.
- Replace it if it looks dirty or clogged.
- Some filters are inside the tank—check your manual.
Prime The Engine
Most snow blowers have a primer bulb. Press it 3-5 times to pull fuel into the carburetor before starting.
Oil: The Engine’s Lifeblood
Proper oil is essential for smooth starts and long engine life.
Check Oil Level And Condition
- Use the dipstick to check oil level.
- Oil should be clear amber (for new oil) or slightly dark (for used oil).
- If oil is black, gritty, or milky, change it.
Change Oil If Needed
- Warm up the engine slightly (if possible) to thin the oil.
- Remove the drain plug and let oil drain fully.
- Replace with manufacturer-recommended oil (often 5W-30 for winter use).
Synthetic Vs Conventional Oil
Synthetic oil performs better in cold weather and can make starting easier. If you live in a very cold area, consider switching.
Battery Care: Electric Start Models
If your snow blower has an electric start, the battery is crucial.
Check Battery Charge
- Use a charger to bring the battery to full charge.
- If the battery is dead and won’t charge, replace it.
Clean Battery Terminals
- Use a wire brush to remove corrosion.
- Apply dielectric grease to prevent future corrosion.
Test Electric Starter
- Plug in the starter and try it before the first snow. It’s better to discover issues now than during a blizzard.
Spark Plug: Small Part, Big Impact
A worn or dirty spark plug can prevent starting.
Inspect The Spark Plug
- Remove the plug and check for carbon build-up or cracks.
- Gap should match the manual’s specs (usually 0.028-0.030 inches).
- Replace if worn or fouled.
Reinstall Or Replace
- Use only the recommended type and torque to specs.
- Always reconnect the spark plug wire securely.
Air Filter: Breath Of Fresh Air
Snow blowers need a clean air filter for proper engine function.
- Remove the filter and tap out dust.
- Replace if wet, clogged, or damaged.
Some models have a foam filter—wash with mild soap and water, then dry completely.
Belts, Cables, And Controls
These parts control the drive system and auger. They often stiffen or crack during storage.
Inspect Belts
- Look for cracks, fraying, or glazing.
- Replace if worn—don’t wait for a break.
Check Cables And Levers
- Move handles and levers to ensure smooth action.
- Lubricate with light oil if stiff.
Adjust Tension
- Follow the manual to adjust belt and cable tension.
- Too loose: Auger won’t spin.
- Too tight: May cause premature wear.
Auger, Impeller, And Chute
These parts move snow. If stuck or damaged, they can stop the blower from working.
Turn Auger By Hand
- It should spin freely with no grinding.
- Remove any ice, rocks, or sticks.
Check Shear Pins
- Replace any broken or missing pins.
- Never use a regular bolt—shear pins are designed to break safely.
Inspect The Chute
- Ensure the chute rotates smoothly.
- Clear blockages and lubricate the rotation mechanism.

Step-by-step: How To Start Snow Blower After Storage
After your inspection and maintenance, you’re ready to start the machine:
- Move the snow blower outdoors—never start in an enclosed space.
- Check fuel and oil levels one last time.
- Prime the engine (if your model has a primer).
- Set throttle and choke to the recommended position (usually ‘full’ for cold starts).
- Engage safety key (if required).
- Pull the starter cord firmly, or use the electric start.
- Let the engine run for a few minutes to warm up.
- Test auger and drive controls to confirm smooth operation.
If it doesn’t start after three attempts, wait a few minutes before trying again. Over-priming or flooding is common—give excess fuel time to evaporate.
Common Problems And How To Fix Them
Even with preparation, problems can happen. Here’s what to check if your snow blower won’t start:
Engine Turns Over, But Doesn’t Start

- Confirm fuel is reaching the carburetor—smell for gas at the plug.
- Try fresh gas and a new spark plug.
Engine Does Nothing
- Battery may be dead (electric start models).
- Safety key may not be inserted.
- Check for loose wires or fuses.
Engine Starts But Runs Poorly
- Carburetor may need cleaning.
- Air filter may be clogged.
- Old fuel may still be in lines—run until it clears.
Auger Or Drive Won’t Engage
- Belts may be loose or broken.
- Cables may need adjustment.
- Shear pins may be broken.
