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.
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.
I replaced the fuel line and filter and can now see that no fuel comes up the line to the carb. More than likely the carb needs rebuilt but if somehow the impulse hole gets blocked by a gasket shifting or improperely installed it won’t work at all. I would venture a guess that 90 percent of the chainsaws ,weed wackers ,blowers and other two cycle engines I work on the problem can be traced to a faulty carb from deteriated parts.
