If you disconnect the fuel line from the carb and do not plug it, then turn saw on its side or top. See if fuel comes spilling out, or just weeps out fuel line content and stops. Just take your gas cap into your local saw shop and ask for a vented cap in the same size.
If the operator has repeatedly been trying to start the chainsaw through the recoil starter system, they may have accidentally flooded the engine with fuel. 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. Gasoline will start to deteriorate if left unused and sitting, so if the chainsaw hasn’t been started in a while, be sure to check that old fuel is not collecting inside the chainsaw.
I’ll share everything you should know about what running rich or lean means, how you can check and adjust your chainsaw if it’s not running exactly as it should run. If you are unsure if your chainsaw is running rich, lean, or just right, there are ways to check it yourself without having to take the entire chainsaw apart or having too much knowledge about how everything inside the saw works. There are some easy tricks you can use to check if your chainsaw is running rich or lean.

Does a 2 stroke have a fuel pump?
In a two-stroke engine the pulse tube of the fuel pump is connected to the engine crankcase. As the piston ascends and descends the pressure in the engine crankcase transitions between positive and negative.
Why does my chainsaw bog down when I give it gas?
If your chainsaw is bogging down when you give it throttle, this is often a sign of improper gas-to-oil ratio. If there is too much gasoline in relation to the amount of oil used, this is known as a “rich mixture” and can cause the chainsaw to run poorly.
Can you clean a chainsaw fuel filter?

How do you diagnose a fuel system problem?
A fuel system should be carefully tested for pressure, volume, and electrical integrity before condemning the fuel pump. Often the first step in diagnosing a faulty fuel system is to simply listen.
