Just did mine (twice), you should have the carbs off in ~15 mins. Like others said, there are many tutorials, so I won't repeat. But I will give you the points I had to learn on my own.
1. Be sure to get the right phillips screw driver, otherwise the screws inside the carb (i.e. Needle valve pivot bar, seat retainer, etc.) will strip. Have a back out set handy. I found a ratcheting multi-set at Home Depot that worked really well (Husky brand)....but I stripped a few before I found it.
2. OSD Marine sells a pretty good OEM kit, and it comes with socket screws, which allow you to torque harder to get better seals. It's alittle expensive, so you could go to Fastenal and source replacements for yourself... It may be cheaper.
3. I would consider replacing all the internal phillips screws with socket screws. Like before, just take the originals in to Fastenal, and they will find suitable replacements.
4. If you replace screws go back with new lock washers, or use blue locktite.
5. Make sure you check to see if the carbs linkages are aligned before you separate them, and check to see how they are interlinked. This is not described in the manual, and I couldn't find a any on line resources to help.
6. You might want to check pop offs before you disassemble, just as a reference.
7. If you hit any road blocks, ask first, there are some very helpful people here.
Good Luck!
