It's no sweat, really.. I jsut did mine for the first time and did it solely with the gas in the bowls..
Maybe it was so easy because I'm used to sync'ing slide carbs with the whole lock-nut thing goin on... even got good enough at that to do it with the bowl-fulls..
the lines connect pretty easily,, you just yank off those little caps on top of the carbs, hook it all up, plug the vaccuum hose, and off you go..
good luck
