Carb adjustment for dummies?

Ok, so when I bought my '80 KZ750G Twin the owner had just gotten done rebuilding the carbs, so I'm assuming they're clean. He never had the bike running so I think that the reason the bike won't idle at all is because the carbs haven't been adjusted. Does anybody know of a resource that could guide me through tuning and synching this particular bike? Or could somebody walk me through it? I think I could muddle through if I knew which screws adjusted what. Thanks in advance!
