Common Fuel Problems
Fuel problems often cause an Ariens snowblower not to start. The fuel system needs clean, fresh gasoline to work well. Old or dirty fuel parts can block the flow of gas. This stops the engine from getting the power it needs to run. Understanding common fuel issues can help fix the problem quickly.
Effects Of Old Gasoline
Gasoline loses quality over time. Old gas becomes thick and sticky. It can clog fuel lines and the carburetor. This stops fuel from reaching the engine. Using fresh fuel helps the snowblower start smoothly. Always drain old gas before storing the machine.
Carburetor Blockages
The carburetor mixes air and fuel for the engine. Old gasoline can leave varnish inside the carburetor. This buildup blocks fuel jets and passages. A blocked carburetor causes the engine to stall or not start at all. Cleaning or rebuilding the carburetor often solves this issue.
Fuel Filter Clogs
The fuel filter catches dirt and debris. Over time, it can become clogged with particles. A clogged filter restricts fuel flow to the engine. This leads to poor engine performance or no start. Replacing or cleaning the fuel filter keeps the fuel system clean and efficient.

Spark Plug Issues
The spark plug plays a vital role in starting your Ariens snowblower. It creates the spark needed to ignite the fuel and air mixture inside the engine. Problems with the spark plug can stop the engine from starting altogether. Checking the spark plug is one of the first steps to fix a snowblower that won’t start.
Dirty Or Fouled Spark Plugs
Spark plugs can get dirty or fouled over time. Carbon, oil, and dirt build up on the plug’s tip. This buildup stops the spark from forming properly. A fouled spark plug will cause weak or no ignition. Cleaning or replacing the spark plug often solves starting problems. Regular maintenance keeps the plug clean and the engine running smoothly.
Incorrect Spark Plug Gap
The spark plug gap is the distance between the center and ground electrodes. If this gap is too wide or too narrow, the spark may not jump correctly. An incorrect gap weakens the spark or stops it completely. Check the gap with a feeler gauge and adjust it to the manufacturer’s specifications. Proper gap setting ensures strong spark and easy starting.
Safety And Control Settings
Safety and control settings play a key role in starting your Ariens snowblower. These settings ensure the machine runs correctly and prevents accidents. Incorrect settings can stop your snowblower from starting. Check these controls before troubleshooting other parts.
Fuel Shut-off Valve Position
The fuel shut-off valve controls gas flow to the engine. Make sure the valve is open. When closed, fuel cannot reach the carburetor. This stops the engine from starting. Locate the valve near the fuel tank. Turn it to the “on” position to allow gas flow.
Safety Key Placement
The safety key must be in place for the snowblower to start. This key acts as a switch to complete the electrical circuit. Without it, the engine will not crank. Insert the key fully into its slot. Check for dirt or damage that might block proper contact.
Choke And Throttle Adjustments
The choke controls air flow to the engine during start-up. Set the choke to “closed” or “start” for a cold engine. The throttle controls engine speed. Set it to “fast” or “run” after the engine starts. Incorrect choke or throttle settings can prevent ignition.
Step-by-step Troubleshooting
Troubleshooting an Ariens snowblower that won’t start requires a clear, simple process. Follow each step to identify and fix common problems. This method saves time and prevents unnecessary repairs.
Start by checking the fuel, spark plug, and fuel filter. Then, clean the carburetor and verify the switch and key settings. Each step targets typical causes of starting failure.
Replacing Old Fuel
Old fuel breaks down and causes blockages. Drain the gas tank completely. Fill with fresh, clean gasoline. This helps the engine run smoothly and start easily.
Inspecting And Cleaning Spark Plug
Remove the spark plug carefully. Check for dirt, carbon buildup, or cracks. Clean the plug with a wire brush or replace it if damaged. A good spark plug is vital for ignition.
Checking And Replacing Fuel Filter
Locate the fuel filter on the fuel line. Inspect for dirt or clogs. Replace the filter if it looks dirty or old. A clear filter ensures proper fuel flow to the engine.
Cleaning The Carburetor
Carburetors often clog from stale fuel. Remove the carburetor and clean jets and passages with carb cleaner. Reassemble carefully. This restores fuel flow and engine performance.
Verifying Switch And Key Settings
Check the ignition switch position and key settings. Ensure the choke is in the correct place for starting. Confirm safety switches are engaged properly. Incorrect settings can prevent the engine from starting.
Preventive Maintenance Tips
Preventive maintenance plays a crucial role in keeping your Ariens snowblower reliable. Regular care helps avoid common problems that stop the engine from starting. Simple steps can extend your machine’s life and improve performance. Follow these tips to keep your snowblower ready for winter’s challenge.
Proper Storage Techniques
Store your snowblower in a dry, sheltered place. Avoid damp areas that cause rust and damage. Clean the machine thoroughly before storage. Remove all dirt, snow, and debris from moving parts. Drain the fuel or add a fuel stabilizer to prevent gum buildup. Cover the snowblower with a breathable tarp to protect it from dust. Check tires and belts for wear, and adjust or replace if needed.
Winterizing Your Snowblower
Prepare your snowblower for winter by performing a thorough check-up. Change the oil to keep the engine lubricated. Inspect the spark plug and replace it if fouled or worn. Clean the carburetor to remove any old fuel residue. Empty the fuel tank or fill it with stabilized fuel. Lubricate all moving parts, including augers and chute controls. These steps prevent starting troubles in freezing weather.
Regular Fuel System Care
Fuel system issues often cause starting problems. Use fresh gasoline to avoid stale fuel clogs. Check the fuel filter regularly and replace it if dirty. Clean the carburetor jets to maintain proper fuel flow. Add fuel stabilizer if storing the snowblower for long periods. Avoid leaving fuel in the tank over summer months. This routine keeps the fuel system clear and reliable.
