When the snow is piling up outside, the last thing anyone wants is a snow blower that won’t start. It can be frustrating to pull the cord multiple times, only to be met with silence. However, before giving up and calling a repairman, there are many simple steps that can be taken to troubleshoot the issue.
One of the first things to check when a snow blower won’t start is the fuel tank. Make sure there is enough gas in the tank and that the fuel shutoff valve is in the “on” position. If the fuel is old, it may need to be drained and replaced with fresh gas. Additionally, check the spark plug and air filter to make sure they are clean and in good condition. These simple maintenance tasks can often solve the problem and get the snow blower up and running again.
Diagnosing the Issue
When a snow blower won’t start, it can be frustrating and time-consuming to figure out why. However, by following a few simple steps, you can diagnose the issue and get your snow blower up and running again.
Checking the Fuel System
One of the most common reasons why a snow blower won’t start is due to issues with the fuel system. Start by checking the fuel tank to ensure it has enough gas. If the gas is old or stale, it can cause problems with the engine. In this case, it’s recommended to drain the old gas and replace it with fresh fuel.
Inspect the fuel lines and the fuel shut-off valve for any signs of damage or leaks. If there are any issues, replace the damaged parts. It’s also recommended to add a fuel stabilizer to the gas tank to prevent ethanol buildup and varnish in the carburetor.
Inspecting the Ignition System
Another common issue that can cause a snow blower not to start is a problem with the ignition system. Start by checking the spark plug for signs of damage or wear. If the spark plug is dirty or fouled, clean it with a wire brush and carburetor cleaner. If it’s damaged, replace it with a new one.
Check the ignition coil and spark plug wire for any signs of damage or wear. If there are any issues, replace the damaged parts. You can also use a spark plug tester to determine if there’s a spark. If there’s no spark, it’s likely an issue with the ignition system.
Evaluating Starting Mechanisms
If the fuel and ignition systems are functioning properly, then it’s time to evaluate the starting mechanisms. Check the starter rope for any signs of damage or wear. If it’s damaged, replace it with a new one.
Check the switches, choke, throttle, and choke cable for any issues. If there are any problems, replace the damaged parts. If the snow blower has an electric starter, ensure that it’s plugged in and the battery is fully charged.
By following these steps, you can diagnose the issue and fix your snow blower. Remember to use caution when working with gasoline and always refer to the owner’s manual for specific instructions.
Preventive Measures and Maintenance
Regular Maintenance Routines
Regular maintenance routines are essential to keep a snow blower running smoothly and prevent it from failing to start. The first step is to check the oil levels and top up as necessary. It is also important to change the oil regularly as specified in the manufacturer’s manual.
The air filter should be cleaned or replaced regularly. A dirty air filter can restrict airflow to the combustion chamber, leading to poor engine performance. The filter should be cleaned with compressed air or replaced if it is dirty.
The carburetor should also be checked regularly for any dirt or debris that may have accumulated. A dirty carburetor can cause starting problems, and cleaning it with a wire brush and carburetor cleaner can help resolve this issue.
The belts and shear pins should be checked for proper tension and replaced if they are worn or damaged. The fuel lines and fuel filter should also be inspected and replaced if necessary.
Addressing Common Winter Issues
During the winter season, a snow blower may experience several issues that can prevent it from starting. Moisture can accumulate in the fuel tank, causing the fuel to become contaminated. It is essential to use fuel with the correct octane rating and add a fuel stabilizer to prevent moisture buildup.
Compression problems can also occur in cold weather, making it difficult for the engine to start. Starting fluid can be used to help start the engine in such cases.
If a snow blower fails to start, it may be necessary to take it to a repair shop. Amazon Associate and affiliate links can be used to find a reputable repair shop.
Regular maintenance routines are crucial to keep a snow blower running smoothly and prevent it from failing to start. By following these preventive measures and maintenance tips, a snow blower can be kept in top condition and ready for the next snowstorm.
