this can happen when the petrol gets heated by the engine and ' boils' . shouldn't happen on modern kit .
does the saw still have compression ? -with the saw switched off , try picking it up by the stater cord - if the cord comes out ,and the saw stays on the floor , it's bad news .
otherwise , buy it a new spark plug , and clean out the gap between engine casing and fuel tank .good luck .
