Fuel lines carry fuel from the tank to the carburetor. The carburetor then injects the correct mixture of fuel and air to the engine for combustion. If you’ve left fuel in your machine, including the fuel lines, for a long period of time, such as over the winter, the fuel lines can become clogged. Additionally, dirt and debris can enter the fuel lines through a damaged fuel filter. To check for this, you can disconnect the fuel lines and either visually inspect them, or attempt to blow through one end. If a clog is detected, it is important to check the condition of the fuel filter, as it is designed to prevent debris from entering the lines. When the lines are clogged, they will not allow enough fuel to reach the carburetor, and eventually your engine will run lean, meaning it will have too much air relative to the amount...

When the lines are clogged, they will not allow enough fuel to reach the carburetor, and eventually your engine will run lean, meaning it will have too much air relative to the amount of fuel. Similarly, if the fuel lines are cracked and leaking, it can also result in a lack of fuel in the carburetor. If the lines are clogged, you may be able to clean them. This may make your edger less difficult to start. However, cracked fuel lines will likely need to be replaced, particularly because leaking fuel can become a safety hazard.
