Hi guys,
Great game, but I'm stuck on one bit and a walkthrough isn't helpful. In particular, I'm trying to get the floating robot out of the courthouse line. The walkthrough has you speak to the floating robot first, then go into the sewers, get the car engine, and trade the engine for the motor to give to the floating robot.

Only... I did the sewers first, got the engine, traded for the motor, fixed the motor with the copper wiring, and attempted to give it to the robot, which prompts the flavor text "It's very excited." That's it. No dialogue, it doesn't leave the line. I notice the walkthrough calls the motor "Gimbal's Motor," while in my inventory it's just "Motor"... how do I identify it? How do I proceed? Help!
