My car does not have a fuel shuttoff solenoid. However, it does have an electric fuel pump. I could cut the power to the fuel pump, but there is no point in that. The fuel pump provides fuel to the carb at 3psi. It is automatically controlled by the float valve in the carb. When there is room in the carb for more fuel, the float lowers and opens the valve. The fuel then enters the carb and fills up the float tank. When the float tank is full, the valve is closed, but the fuel pump continues to pump though it is a sloppy pump, the fuel doesn't move in the line.
I don't use the engine for braking. I want to use as little brakes as possible to maximize my coasting. If I used the engine for braking, it would simply restart since it is the same as bump starting.
