Just before we look at the most likely reason your saw won’t idle, we’ll need to check some of the basics, and I’ll fill you in on why they’re important, or if you want to skip all this, go ahead and slide on down to the “Adjusting the idle screw” below. If the chain is moving while the saws idling, then back the idle screw out a 1/4 turn until the chain stops, this fine-tuning can now be done with the saw idling. If the saw still won’t idle, you have cleaned the air filter, got fresh gas mixed correctly, the plug is clean & gaped, and adjusting the idle screw hasn’t worked.
High/Low carburetor adjustment and Idle screws allow the proper airflow through the engine. No matter whether you set this too high or too low- it will cause the engine to die at idle. The simplicity of a 2 cycle engine makes it fairly easy to diagnose and solve the problems you may experience when working with your chainsaw.
Your chainsaw will only idle for about 5 to 10 seconds after you let off the throttle and then it will shut down. A bad fuel line will cause the chainsaw to run lean, and this means it will only run at idle for 5 to 10 seconds before it shuts off completely. An air leak around the intake boot or head gaskets will result in lower compression pressures and your chainsaw won’t idle properly.
Finally, if your chainsaw resounds well but dies off when working under a load, then it might also be an idle problem as well. If you can start your chainsaw easily, and it runs smoothly without any issue, then the idle is working just fine, and there’s no need to tamper with it. Finally, if your chainsaw resounds well but dies off when working under a load, then it might also be an idle problem.
