The bolts holding the carbs will not clear without taking the rod that goes through the middle out. Each is held in place by what looks like a straight cotter pin...how do I remove the pin and probably as important, how do I put it back?

Wait, don't take those pins out...do it like this:
Loosen the mounting nuts with an open end wrench until you can turn 'em with your hands.
Using both hands, start removing both nuts simultaneously. Pull the carb (and the shaft that's in your way) toward you as you remove the nuts.
Not sure I described that well enough.
Other words, when the nut gets out near the end of the stud, the carb will move toward you, and the shaft won't be in the way anymore.
If that is unclear let me know I'll try again.
If the carb is particularly dirty, two things you should do is remove the jets to clean them out individually, and remove the core plugs to clean behind 'em.
Depending on what year your motor is, you'll have either 2 or 3 jets per carb; the hi-speed jet is in the bowl behind the drain plug, the idle jet is behind a screw plug above the venturi, and the off-idle (intermediate) jet (if equipped) is behind a screw plug on the port side, at a 45º angle to the front.
Don't use a regular screwdriver on the jets, too much liklihood of scratching or scoring and that'll ruin 'em. You need a special tool, which you can fabricate using a screwdriver and dremel or belt sander. Basically cut the screwdriver off flat, and grind the end into a perfectly flat tab as shown here:

The core plugs are those convex lead "contact lense" looking things in your rebuild kit. Remove the old ones by drilling a hole in 'em, insert a small screwdriver or punch and pop 'em out. Go slow so you don't hit too hard when it breaks through, but don't worry, there's a cavity underneath so your drill bit won't damage anything. Spray aerosol carb cleaner up into every nook & cranny you can get it to. To install the replacements, just drop 'em into place and flatten 'em out with a hammer and punch (a small socket works pretty well for this).
If you don't have rebuild kits, I highly recommend you get some (about $12 apiece on iboats.com), you'll have wasted a lot of time if a re-used gasket or o-ring fails, or the float valve is worn down, or whatever.
Be sure to replace the valve needle *and* seat.
Unless they're really contaminated , the overnight soak and spraying through all the orfices with compressed air (or aerosol carb cleaner) does the trick.

My husband said remove it with a punch. It's a tool, not your fist.
