Why does my Stihl trimmer keep cutting out?
The trimmer can sputter and stall if it isn’t getting enough fuel, and that can happen simply because the fuel filter is dirty. Fuel filters are inexpensive, and it’s more practical to replace a dirty one than it is to try to clean it. On most models, it’s in the gas tank or on the cap.
Is it illegal to own a carburetor adjustment tool?
it is illegal by EPA regulations to sell carburetor adjusting tools and illegal to buy them unless you are a servicing dealer.
Should trimmer head spins at idle?

What is the La adjustment on a Stihl?
The LA setting on Stihl chainsaws is controlled by a screw on the outer housing of the engine that adjusts the flow of fuel and air through the carburetor. These screws adjust the engine’s output at low and high speeds.
