Introduction
Is your snowblower not staying running, leaving you with a snow-filled driveway? Don’t worry! This article will guide you through the possible causes of this problem and provide practical solutions to get your snowblower back in action. We’ll dive into specific examples, brand names, and precise steps to ensure your snowblower remains operational throughout the winter season.
Common Causes of Snowblower Problems
Dirty or Clogged Carburetor
A dirty or clogged carburetor is a common cause of snowblower malfunctions. The carburetor, found in brands like Briggs & Stratton and Tecumseh, mixes air and fuel to create the right mixture for combustion. Over time, dirt, debris, and fuel residue can build up and obstruct its performance, causing your snowblower to stall or shut down.
Old or Contaminated Fuel
Old or contaminated fuel is another frequent issue, particularly if your snowblower has been sitting idle for an extended period. The fuel may have become stale or water-contaminated, leading to poor engine performance and difficulty staying running. Snowblower manufacturers, such as Toro and Ariens, recommend using fresh fuel with a stabilizer to prevent this issue.
Blocked Fuel Lines
Fuel lines can get clogged with dirt or debris, impeding fuel flow to the engine. This can result in the snowblower stalling or failing to start at all. Manufacturers like Honda and Husqvarna recommend regular inspection and cleaning of fuel lines to ensure smooth operation.
Faulty Spark Plug
A worn-out or damaged spark plug can cause your snowblower’s engine to misfire or not start at all. Regularly inspecting and replacing the spark plug, as recommended by brands like MTD and Craftsman, is essential for optimal engine performance.
Clogged Air Filter
A clogged air filter restricts airflow to the engine, causing it to run poorly or stall. Brands like John Deere and Cub Cadet recommend regular maintenance to prevent this issue.
How to Fix a Snowblower That Won’t Stay Running
Cleaning the Carburetor
To clean the carburetor of a snowblower, such as a Briggs & Stratton model, follow these steps:
- Remove the carburetor by disconnecting the fuel line and removing the mounting bolts.
- Disassemble the carburetor.
- Clean each component with a carburetor cleaner like Gumout or Berryman B-12 Chemtool.
- Reassemble the carburetor.
- Reattach it to the snowblower and test the engine.
Replacing the Fuel
To replace old or contaminated fuel in a Toro snowblower, follow these steps:
- Drain the fuel tank and clean it thoroughly.
- Refill the tank with fresh fuel, ensuring it meets the manufacturer’s recommendations (usually unleaded gasoline with a minimum octane rating of 87).
- Add a fuel stabilizer like STA-BIL or Sea Foam to extend the life of the fuel.
Clearing Fuel Lines
To check and clean the fuel lines of a Husqvarna snowblower, follow these steps:
- Inspect the fuel lines for signs of blockage or damage.
- If clogged, remove the lines.
- Clean the lines with a fuel line cleaner like Red Line or Lucas Oil, or use compressed air.
- Replace damaged lines if necessary.
- Ensure all connections are secure when reassembling.
Checking and Replacing the Spark Plug
To inspect and replace the spark plug of a Craftsman snowblower, follow these steps:
- Remove the spark plug from the engine.
- Inspect the electrode for wear and the insulator for cracks or damage.
- If necessary, replace the spark plug with a compatible one like NGK or Champion.
- When installing a new spark plug, ensure it is properly gapped according to the manufacturer’s specifications (usually between 0.028 and 0.031 inches).
- Reinstall the spark plug and test the engine.
Cleaning or Replacing the Air Filter
To clean or replace the air filter of a John Deere snowblower, follow these steps:
- Remove the air filter from the snowblower.
- Inspect the filter for dirt, debris, or damage.
- If the filter is reusable, clean it with a mild soap and water solution, and let it dry completely before reinstalling.
- If the filter is not reusable or is damaged, replace it with a new one.
- Reinstall the air filter and test the engine.

FAQs
- How often should I change the oil in my snowblower? It’s generally recommended to change the oil in your snowblower at least once per season or after every 25-30 hours of use, depending on the manufacturer’s recommendations.
- What type of fuel should I use in my snowblower? Always use the fuel type recommended by the manufacturer. Typically, a snowblower requires unleaded gasoline with a minimum octane rating of 87.
- Can I use a fuel additive to prevent fuel-related problems? Yes, using a fuel stabilizer can help prevent fuel-related issues such as stale fuel or fuel separation during storage.
- Why does my snowblower’s engine smoke while running? Engine smoke can be caused by several factors, including an overfilled oil reservoir, burning off residual oil, or worn engine components. If the problem persists, consult a professional.
- How can I prevent my snowblower from clogging with snow? Ensure the auger and chute are clear of snow and ice before each use. Spray a non-stick lubricant on the auger and chute to help prevent snow from sticking and clogging the machine.
