Tony's procedure is good. Remember, the purpose in syncing the carbs is to
have each cylinder receiving the same amount of air for a given throttle
lever position. Assuming the carbs are equally clean and that the valve
mechanism (2 stroke or 4 stroke) has the same timing per cylinder, each
cylinder should deliver the same power if the carbs are in sync. Using
vacuum gauges, etc, isn't any better than visually aligning the butterflies
looking down the throats. Usually, one carb is designated the 'reference'
carb and the others are adjusted to match that one.

Loosen all the linkage screws on the side of the carbs. With the throttle
at idle position, all the throttle plates should be down against the body.
Tighten all the linkage screws.
Now open the throttle to wide open and verify all throttle plates are
setting flat.
If one is out slightly - loosen and adjust to flat as the others.
Now back to neutral and verify all plates are the same.

Very simple on these engines.

Could someone have pity on me and point me to some kind of resource
describing how to sync three carbs.

I goofed and turned the screws on my Force 85's carbs instead of the
manifold mounting screws (long story, suffice it to say I wasn't paying
attention). I heard something about listening through a hose or
something once before, but I have no idea what I'd be listening for. I'm
handy with tools and have a workshop (I live on a ranch, it's a
necessity). I've worked on pletny of things from shredders to tractors
and Jeeps and lawn mowers, but none of them have 3 carbs!
