"Who here can fix my problem? Now mind you, I'm not going to TELL you the problem or even all the symptoms, I'm going to quiz you and dribble out one or two clues at a time and see how long you'll play." Do you ever get people that walk into your shop and play you that way face-to-face, Ian? I kinda doubt it, its a lot easier to be a belligerant jerk through the anonymity of a keyboard and internet connection.
I have to say I'm kinda proud of the way this group as a whole responded. It would probably be even better if we'd just ignored the damnfool, but then he'd just have changed sock-puppet names and tried again (in fact, he already did post another more detailed genset engine question under a different name, and didn't get a SINGLE response). Which also tells me the damn thing STILL isn't running :-)
