I remember when I first got my truck I was terrified of the carb. Just now getting into it and it's not nearly as bad as I had anticipated. Just take tons of pics and label everything in ziploc baggies. Also having a "cheat sheet" that comes with your rebuild kit (or if not I can PM you a pdf of the one from my thread) is priceless. It helped me ID everything for the baggies and is useful in guiding you once it comes time to reassemble everything.
Have fun!
