Many people believe repairs to their gasoline-powered products are complicated, but that isn't the case with a grass line trimmer. In fact, a 2-cycle line trimmer is one of the simplest lawn products to repair.

Our grass line trimmer repair help page offers troubleshooting tips and common parts used on a two-cycle trimmer, making it easier to find the problem and fix it. The easy repair guides below can help get your trimmer back in working order in less than 30 minutes, helping to make your life a bit less complicated and put the finishing touches on a well-groomed yard.

Cracked or clogged fuel line

The fuel lines on a line trimmer deliver the gas where it needs to go. A clogged fuel line won't let gas through, and a cracked line will leak. The instructions for this easy fix are in our DIY repair guide How to replace a line trimmer fuel line.

Bad carburetor

The carburetor in a line trimmer mixes fuel and gas. A bad carburetor can keep the engine from starting. Rebuilding a carburetor is easy to do following the instructions in our DIY repair guide How to rebuild a line trimmer carburetor. You can also replace the complete carburetor assembly; just follow the instructions in our DIY repair guide How to replace a line trimmer carburetor.
