How to Clean a Clogged Gas Trimmer


A gas-powered weed trimmer can help you maintain the trimmed, manicured look of your lawn and backyard, but not when it's clogged. Various parts of the power tool can get clogged with both yard debris and engine deposits. Periodically clean your weed trimmer to maintain its proper operation and remove anything that may be clogging it and keeping it from running at its optimal power levels.

Step 1

Turn off the weed trimmer. Inspect the end of the weed trimmer's head, where the string spool is located. Vegetation typically collects here, clogging the spinning string mechanism and causing the trimmer to shut down. Use your hands and clear away all debris.

Step 2

Loosen and remove the muffler's mesh screen, found on the rear end of the weed trimmer, using a screwdriver. Wipe the screen down with a rag to clean off all the black deposits. Unlike electric weed trimmers, gas trimmers often build up a collection of carbon deposits on the muffler's screen, which can slow the tool's performance.

Step 3

Inspect the weed trimmer's sparkplug. Over time, engine deposits can build on the plug and impair the engine start-up process. Remove the plug and wipe it with a rag. The plug is usually located on the top or side of the tool's engine block. If you're unsure of its exact location, consult your user manual.
