Check the carb boots for cracks, make sure that the boot to reed block bolts are tight, also make sure the plugs are on all of the primer nipples (if it does not have a primer installed). You said that you already cleaned the carbs, so you shuld know that the pilot circuits are not clogged. Use carb cleaner to check the crank seals, not something more volitile like starting fluid. Does the engine die when the choke is disabled or does it rev higher?
