when do you know
that is time to rebuild your carb? Also how difficult is this process really. I don't know much about carb's I'm a fuel injected kind of guy, but I'd really like to learn. I think the Haynes manual says something about this but I really hate that manual. It isn't all that helpful.

When gas mileage or driveability are suffering, or you failed emissions, and a fresh tune-up didn't help.
It's a few hours worth of a job. You need a clean work bench to spread things out and keep them organized, a large can of real carb cleaner that is big enough to put the entire main body into to soak, and an air compressor to blow everything out after soaking. If you try it without all of these things, you're going to regret it.
You'll also need a high impedence multimeter to set the throttle position sensor, and some special tools to do some other adjustments (<$10 at the parts store).
The Haynes Rochester manual is a pretty good book. So is Doug Roe's Rochester book.
