How to troubleshoot your Lehr line trimmer when it runs rough

If your line trimmer runs rough, the fuel may be the issue. Fuel left in the tank for months can absorb moisture and fail to ignite, so always drain the fuel before winter storage or use a fuel stabilizer. Replace the old fuel with fresh gasoline and consider replacing the fuel filter at the same time. Regular maintenance, such as performing a line trimmer tune-up, helps ensure the engine runs smoothly.

Inspect the fuel lines for cracks, as these can allow air into the system, disrupting performance. If the fuel system is in good shape but the problem persists, you may need to rebuild the carburetor.

What to do when your Lehr line trimmer won't start

If your line trimmer won't start, ensure the fuel tank contains fresh gasoline. Old gas can accumulate water and reduce combustion efficiency. Replace the fuel and add a stabilizer to maintain freshness.

Next, check the fuel lines for cracks that allow air into the carburetor instead of fuel. If the fuel lines are intact, inspect the carburetor; a dirty carburetor may need rebuilding or replacement. Finally, check the spark plug for corrosion or deposits on the electrodes and replace it if necessary. To test for compression, remove the spark plug, cover the opening with your thumb, and pull the starter cord. If there’s no pressure, the piston rings may need replacement.

What to do if your Lehr line trimmer is leaking gas

A line trimmer leaking gas can pose safety risks and should be addressed immediately. Inspect the fuel lines, gaskets, and primer bulb for cracks or wear. Replace any damaged components to stop the leak and restore safe operation.
