Atv leaking gas now......?

i took it apart ad cleaned the carb yesterday. and the hose wasnt really big enough for the gas tank and would keep falling off cuz you couldnt get it up on the thing very good (so i took a screwdriver nd try to make the end of the hose wider so it would fit on to the gas tank more). and i put it all back together. and it had a full tank of gas. And i went to take it out today to fine all the gas is gone nd is on the floor. then i put more gas in it and it didnt leak 4rm anywhere.. went bck later nd it was out also so whts up?, do i put a small pin hole in the gas line whe i try to make the end wider or is there sumrhing wrong with the carb?,. btw its only a 4 stroke 50cc atv
