If you are going through all the time and expense to rebuild the carbs you will want to get the best performance from them. The last thing you should do is sync. If you do not have the meters there is a post in the FAQ about how to bench sync them before you reinstall. That will get you close and all you need is a set of drill bits.
Be sure to take alot of pics even before you remove them. You will be surprised at how you can forget where stuff goes. And everything that comes from carb #1 goes back into carb #1. Do not mix and match parts that you are putting back in. Use containers marked carb #1, #2, etc. Good luck with it...
