Why is my Stihl Chainsaw not starting?
The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel will evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.

How do you adjust a carburetor on a Stihl chainsaw?
To do this, turn the “L” screw clockwise as far as it will go, using a flat-head screwdriver, then turn it counterclockwise as far as it will go. If it turns more than one complete revolution, it’s a type A carburetor, and if it turns less than one revolution, it’s a type B carburetor.
Why does my chainsaw dies at full throttle?
If the filter becomes clogged, not enough fuel will reach the engine for it to run properly. Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle.
How do you start a stubborn chainsaw?
Activate the choke by moving the lever to the full choke position and pull the starter rope 3 or 4 times to start the engine. If that doesn’t work, move the choke lever to half choke and pull the starter rope, 6 times maximum, to start the engine.
