The gas you left in the carborator has turned into bubble gum..shut the fuel off and remove the carb..spry it with carb cleaner....and while you have the gas line off the carb...drain the tank and start with fresh fuel...check your oil and next year put fuel stabilizer in it at the end of the year... Dont do it at the end of the year....each time you buy gas for your lawn & garden equipment,always use stabilizer, always, you never know when is going to be the last time you are going to use it for the season, and gas only has a 30 day shelf life...only ! Stabilizer or not, if I don't plan on using gasoline-operated lawn and garden equipment for at least 30 days, I drain the fuel tank and then run the motor until all the gas is gone. The way I see it, no gas = no problem.
