Anyone know what could be causing this ? Engine will crank and runs well at low rpms but sputters at high rpms and cuts off under a load . New fuel pump , plugs and air filter . Thanks !

sounds like a stuck or sunk float in the carb... putting too much fuel in the float bowl. it might need to be cleaned
