Weed eater, weed whacker, string trimmer — no matter what you call it, here's how to get it running again. Fortunately, gas weed-eater engines are pretty simple, so most DIYers with a few tools and some basic know-how can troubleshoot a stubborn trimmer and get it running. If your trimmer falls into this category, empty the old gas from the fuel tank and replace it with fresh fuel.

Let it sit for several minutes to help loosen and dissolve varnish.

This trimmer has less than 1 hour on it. Just recently it's gotten a little tougher to start and does not run smoothly. It sounds as if it's breaking up, or is miss-firing. It just doesn't have that clean crisp sound. I've gone through the basics and made up a new batch of fuel with premium gas and Stihl mix. I just got a new spark plug but have not yet tried. Can anyone think of anything else specific to this trimmer? I can't see that it should need a carb tune with 30 minutes or so of total run-time. Hey all, I just wanted to report back with a resolution of the problem for those of you intrested in a solution. As is the case with most issues, this was caused by user or operator error. Apparently, I let the sting get too short which caused the trimmer to over-rev to the point it hit the built in rev-limiter.

Beware, however — taking apart a carburetor marks a point-of-no-return, of sorts. I have tested this on 2 of my pieces, and the one with Reg def runs rough after about 15 min of continuous use, where as the one with Prem mix, ran great United States.

The use of trimmers is an important part of lawn care, and when they malfunction, it can be frustrating. STIHL trimmer heads are a great choice for those looking to get the most out of their lawn care equipment. They offer a wide range of features and benefits, including easy-to-use controls, durable construction, and reliable performance. With proper maintenance and use, STIHL trimmer heads can last for many years without needing to be replaced. The clutch is the part of the trimmer that engages and disengages the cutting head from the engine. When this part becomes worn or damaged, it can cause the trimmer head to become stuck in one position and not rotate properly. Additionally, a damaged clutch can also cause the cutting head to vibrate excessively, which can lead to further damage. To troubleshoot this problem, inspect the clutch for any signs of damage or wear. If any damage is visible, replace the clutch with a new one.
