How do you remove the carburetor bowl ? What is the purpose of the electrical connection attached to the carburetor ?

I have water in the fuel system and want to clean the carburetor bowl. Can't see how it is attached.

Use a ground down wrench that will fit between the fuel solenoid and the carb bowl to loosen the solenoid, then remove the solenoid and the bowl. The purpose of the solenoid is that it is suppose to shut off the fuel flow once the key is turned to the off position.
