6lb pump blowing out carb?

one way I've used to clean the tank was I bought a 6ft length of like 3/8" hot galv. chain and dropped it into the tank with a gallon of your favorite solvent and shake it like a maracas, until sufficiently clean. When done rinse thoroughly.
For the lines I use a 10ft length of brass speedo (inner)cable. You can push it in/out manually or even spin it while chucked into a variable speed drill and kinda roto rooter the lines and finally blow them out with compressed air.
