Tried squirt of carburetor cleaner after reading Q&A on another forum. Tried splash of fuel in spark plug hole. Would adding starter fluid to fuel tank do it? Not take carburetor apart. Hope rebuilding carburetor not necessary, as saw started fine, but would not hold idle.
Started easily, but would die before could use. Squirted one second blast of carburetor cleaner into spark plug hole. Now not start. There is spark. New plug, gas, air and gas filters. Inject more carburetor cleaner, or is that what caused problem?
