Ok , looking further into things. It appears there is something similiar to the top of a spray can that is rolling around in the gas tank , something similar to the nozzle. Don't know if it's part of the tank that has broken or something that somehow got in there. As I cut it apparently rolls around eventually plugging up the bottom of the tank. I will have to empty the tank and remove the item. There is a tie cable that holds the tank in , how do I remove that without breaking the tie ?
