More than likely

More than likely a lack of fuel...here's what i do; check for air leaks with starter fluid or wd-40 or equiv. While running spray the carbs, the intake manifold, the end seals, the starter rope side can be diffucult. If the idle picks up you have a leak. If not then with a small pump oil can (spray bottle works too) remove the airbox, start with choke on, release choke. As soon as it starts dying spray gas (oil & gas mix) into intake of carb. If it picks up you need to troubleshoot the fuel system.
Good luck
