Seems that the chainsaw has flooded. leave the chainsaw for a while. then start it (try without choke first) if it floods and cuts out your chainsaw again. check your spark plug is working. if it is then take the carb off. if u unscrew the faces of the carb. you should see what looks like a see-saw with a spring and needle . take the needle out and look that it hasnt been stuck open by any dirt. if it is then it will keep over fueling. if you have an air line try blowing air through that hole also to make sure it hasnt got dirt in thier.also their is 2 butter flys on the carb. (1 for choke and 1 for the throttle.) make sure they are also working.
