Once all throttle connections are completed we checked to be sure that the throttle would work freely before driving the vehicle. At this time it is also good to turn the key on and let the fuel pump pressurize the system. A check of the entire fuel system for any leaks was done before anyone got in for a lap around the block. But once that was complete and A-okay, our big car cruiser was ready to go. And go she did! And a whole lot smoother and more powerful than that old carb-fed mini-Mouse. What a fun (and easily accomplished) reincarnation this big car turned out to be.
