Step 2: Check The Fuel

Add fresh fuel

If you are using the fuel from the previous season, it may cause issues. Some residue may form at the bottom of the fuel tank when the snowblower has been idle. It’s essential to remove this residue to start the machine. You can take a pump to remove the fuel.

It’s also better to get a siphon to clear the fuel entrance. After you are satisfied with the cleanliness, you can add fresh fule and test the snowblower again. Most snow blowers will run using this method.

Add fuel stabilizer

If you cannot clear the residue by physical force, it’s better to use the fuel stabilizers. Basically, it’s a liquid to remove the residue and stabilize the fuel flow.

You can add it to the fuel tank and let it stand for some time. When you have waited for a time specified on the fuel stabilizer operation guide, you can add more fuel and test the snowblower again.

You’ll probably have to pull the cord a few times with full force to run the fuel in the system. It will take some force to allow new fuel in the working chamber.

Snowblowers are like your car. Sometimes it can be hard to start the vehicle in extreme cold.

If the snow blower won’t start after clearing the residue, it can be due to fuel flow problems. You can add extra fuel to the carburetor by pressing the silicon bulb-like structure on the carburetor. This bulb will push more fuel into the carburetor to help the machine start the initial ignition.

Resolve fuel line issues

It’s possible to resolve the fuel line issues by inspecting the small pipe going from the fuel tank to the carburetor.

If there is a blockage in the fuel line, the snowblower will not start. It’s better to check for the blockage first. You can take out the fuel line and blow air through it. The air should pass without resistance.

If there is no blockage issue, you can check for the leakage. Leakage can also prevent fuel entry into the carburetor. You can check for signs of leakage. One part of the pipe will change color if there is leakage.

If this step fails, you can leave the fuel-related issues and check the other parts.
