Add syrup to keg, add water. Close, seal and carbonate. Shake while carbonating, or inbetween carbonating. (Pressurize at 60, disconnect, shake, repeat a few times) check the pressure until around 20ish then carb at 30 for the rest & shake.
Not really worth putting the gas at the other end using this method.
You can just put the keg on it's side and attach the gas normally and let it roll around with your feet back and forth for an hour or so.
