This problem usually comes from using fuel in the saw that has alcohol in it without adding a fuel conditioner. The saw and any other machines using gasoline must be run completely dry of fuel when storing or may sure that the saw has a conditioner mixed with the fuel. Sounds like the power jet portion of the saw is blocked. Typically the only fix is to take the carb apart and open that portion of the carb. The only way to keep this sort of problem from happening is to purchase alcohol free gasoline for your portable gasoline run machines.
