Grass Line Trimmer: Runs rough

If the fuel has been in the tank unused for months, it can pick up moisture and fail to ignite (that's why you should drain the fuel before storing for the winter). Replace it with fresh fuel. You might also need to replace the fuel filter at the same time. Check the fuel lines for cracks and replace them if necessary. If you still have problems after checking those issues, consider replacing or rebuilding the carburetor.

These repairs may help solve your Grass Line Trimmer problem:

Replace the grass line trimmer fuel lines

Fuel line

Fuel lines become brittle over time and can crack or tear. Replace a fuel line that's brittle or damaged. Be careful to install new fuel lines on the engine the same way the original fuel lines were configured.

Replace the grass line trimmer carburetor

Carburetor

The carburetor mixes air and gasoline in the proper proportions to create a combustible gas. If the engine starts and then sputters, or doesn't start at all due to lack of fuel, you might need to replace carburetor. It's often more cost effective and practical to replace the carburetor rather than rebuild it.
