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. Once gas breaks down, varnish, gums and other debris can form inside the carburetor and clog the tiny fuel passages. Remove the air filter and spray carburetor cleaner into the intake. 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.

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.

We use it a lot to trim around posts and on blackberries and the string is forever jaming, not feeding etc. On the other hand we also have the el-cheapo electric trimmers from the big box store and although they don't last too long maybe years at least they work the way they are supposed to. Unfortunately our property is too big for an electric to cover it all. Regards Fred. Sort by Oldest first Oldest first Newest first Most reactions.

The pull cord likely puts more strain on it than anything else could, so maybe that was it. Any advice would be very much appreciated - thanks! Like Summary. Gold Membership.
