Stihl chainsaw carburetors usually have three adjustment screws: one each for idle, low speed and high speed. A clogged fuel filter is often caused by leaving old fuel in the chainsaw. If your chainsaw engine dies at full throttle, check the following parts: the carburetor, fuel lines, fuel filter, air filter, and muffler.
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. If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. The most common problems why a chainsaw does not stay running are: Spark Switch/Plugs.
To resolve any problems with filters you should replace the fuel filter which is usually found in the gas tank and can be removed and replaced quite easily. Issues with fuel can often result from a chainsaw having been sat idle for a long time. If your saw has been in storage for a while, gas left in the carburetor and fuel lines may have started to evaporate, leaving behind a type of varnish which clogs up the system.
“The chainsaw is pretty new, a Poulan 16”. Normal starting routine – prime, choke, pull about 3 times til it fires a little, then push choke off, pull a few more times till it starts. If it was running fine, I’d let that fast idle go 30 sec or so til warmed up, then pull the throtle which kicks off the auto fast, and it should drop into a normal idle mode, ready to start cutting.
