Why does a lawn mower keep dying?

Usually has to do with the carb, every craftsman mower ive ever owned if left sitting for more than a week or 2 ends up with gummed up carbs that will need to be taken apart and cleaned out. most of the carbs have a small bolt on the bottom, so what i do is ziptie the gas line shut and take the bolt off the bottom which will let you remove the bowl off the carb. clean out the bowl and then reassemble and it should be working for you.
