Your floats either need adjusting or you got some crud in the carb. Take the bowl off and adjust the floats and blow out the passages with air.

Default Banshee Carb HELP

Long explanation, compliments of this link.

fuel petcock

Q#26:When I turn the fuel petcock “on”, fuel dumps out the overflow hoses, why?
A#26:Either you need to adjust the float height, or clean the float needle. If you’ve just had the carbs apart or they have been sitting dry for a while, first see if the floats can be unstuck by tapping on the carb bowls with a screwdriver handle. If that doesn’t work you’ll need to remove the carb and check the float height and float needle. Remove one carb top (see Q#22) and set the top assembly aside, then remove the carb body (see Q#20). Set the carb body upside-down on a bench, then remove the float bowl and gasket. Locate the pin that the floats pivot on, and use a small punch to drive the pin to one side (one end is flattened like a nail head so you can only drive it out one direction). Remove the pin and lift the floats straight up, hanging in the center of the metal piece connecting the plastic floats is the float needle. Slide the float needle off the float bracket, and look at the black rubber tip. If there is a speck of dirt on the tip of the float needle or the seat where the float needle sits, it will prevent the float needle from seating and let fuel overfill the bowl, and then run out the overflow hoses (if there is debris, see Q#27). If the tip of the float needle and the seat is clean, check the float height. Hang the float needle back on the float bracket and set the assembly back in place so that the float needle drops into it’s seat and the float bracket pivot holes line up with the holes in the carb body, then reinstall the pivot pin (tap the flattened end lightly to seat the pin). With the carb still sitting upside-down on the bench, measure the distance from the carb body gasket surface (WITHOUT the gasket in place) to the highest point on the black plastic floats (without putting any pressure on the floats). This measurement should be between 20mm and 22mm. If adjustment is necessary, gently bend the metal float bracket on each float to reach the right height. A simple tool can be made to measure the float height out of cardboard, simply cut L-shaped pieces that measure 20mm, 21mm, and 22mm from the top of the L to the top of the leg of the L:



After setting the float height, reinstall the float bowl gasket, float bowl, and carb body. Install the carb slide and top, and if necessary do the other carb. Don’t forget to install the choke tube between carbs, check the carb sync, and if fuel runs out the overflow hoses when you turn the fuel petcock “on”, tap on the float bowls again to see if you can unstuck the floats.

It's not as hard as it sounds. Once you get it right you can charge all of your buddies to do theirs. hehe

Default Banshee Carb HELP

It is just a peice of hose that goes between the carbs. If you look you will see the nipples stick out of each carb. I like to use surgical tubing (Fuel Line) to connect them. If the vent hoses aren't still on your carbs you will see four nipples, just make sure you hook the right tubes together. From my experience it is very hard to crank a banshee that is missing the hose.
