Thank you, that makes perfect sense and I believe that I'm close to being in business. I will take photos of the original "problem" that I had so that you can understand, maybe it will help someone else in the future.
I just tested it out and the fast idle works when the truck is started and then slowly backs off as the choke opens. The only question (and maybe it's operating as designed) is that as soon as the throttle is blipped, the fast idle cancels itself and it drops back to its regular idle. Does that sound right? It wasn't a problem today, but I can see on a cold day if you don't sit and warm the truck up for a minute, it will probably die.
