I did a carb rebuild on the first Toyota I had about 8 years ago. I'd never done one before and I half assed it over a day and a half on a weekend because I needed it the next day for work. it still ran way better than it did before, so...

not too big of a deal if you can afford a little downtime, have a decent set of mini pliers. some compressed air would have been handy when I did mine, and some more time to soak the parts.
