I just got a Simplicity mower with a 14hp engine from a friend at work. The first thing i did was try to start it, no dice. Then i took apart the carb and cleaned it, no dice. then i tried to put gas in the carb and start it and it would only run like 1-2 secs untill the gas i poured in went out. anybody have any sugjestions on what i should try to get it to run?
