just wanna take my carb off,how do i deal with the fuel lines?

It's not going to poor fuel out untill your tank is empty. Just pull them off and point them into a bucket or bottle untill they stop dripping. If they just keep dripping then shove a bolt in there thats slightly wider diameter than the ID of the fuel line. Sometimes the fuel filter up there can keep leaking as it holds a considerable amount of fuel itself. Or just keep the open ends of the lines up higher than the highest point of the fuel system. Since there is no real pressure to force it through it wont leak out

and dont turn the ignition on Or you might get squirted.
