what does the ball do when you pump it? does it get hard when you pump it up?
Fuel filter on motor when was it cleaned or replaced last??
Is the ball still hard after a hour? Might have a bad o ring or something and gas draining back after a while?
Clean carbs as stated, all else fails try running on a portable tank and see what happens
