How does off switch on a chainsaw work?
When the ground switch is off or open the pulse has nowhere to discharge except by jumping the gap on the spark plug creating the spark that causes combustion as it travels to ground. The kill switch is simply a shortcut that prevents normal running function of the ignition system.
Why does my Stihl chainsaw have no power?
When your Stihl MS 170 chainsaw drops its power under full load, it generally means there is an improper mixture of fuel and air in your carburetor. When you depress the trigger, a vent on the carburetor opens, allowing more gas to reach the mixing chamber.
Why will my new Stihl chainsaw not start?
If the engine doesn’t start on the first three or four pulls, the fuel and air mixture becomes fuel rich, and if you continue to pull the starter while the choke is closed, there is too much fuel to ignite and the engine floods. You can simply wait for the fuel to drain, but there is a faster way to clear the engine.
How do you test a switch on a chainsaw?
Check for a bad kill switch by disconnecting the switch’s wire and checking the plug for spark. Do this by unscrewing the plug, holding it by the rubber boot and touching its threads to the engine metal while pulling the starter cord.
What is symbol for on and off?

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.
Why does my Stihl chainsaw stall?
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 may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and cause the chainsaw engine to stall.

How do you start a chainsaw that won’t start?
If you believe fuel has flooded the chainsaw engine, pull the starter cord several times while holding the throttle, dry and replace the spark plug, and then try starting the chainsaw again.
How does a chainsaw magneto work?
The magneto creates the electrical charge needed to fire the spark plug, and the spark plug creates the spark inside the combustion chamber to ignite the gasoline (see How Two-stroke Engines Work for details).
How do you test a Stihl chainsaw coil with a multimeter?
Locate the coil on your chainsaw. Connect the negative and positive cords of the multimeter to the negative and the positive terminals of the coil in your chainsaw and measure the resistance. A brief answer is convenient for those who are short of time but it will not give you the necessary details of the matter.
