Also make sure that your vacuum line from your petcock is hooked up, or plug the port at the carb and use prime on your petcock.

joel ive got a spare set of carbs here, worked perfectly when i yanked em from the bike.
wouldn't be too bad shipping them from NZ 100 + shipping or something and you can have em... has the vent hoses you speak of.

Haha, sorry about jacking your thread, i swear i've never done that before
(usually it happens to me, more than often)
Well it looks like the air screw on carb # 4 is completely stuck,(therefor I cannot adjust **** now...) the threading is toast, and the Flathead grip is toast also! I really don't know if I'm going to be able to get it out guys!
The ONLY thing I can think of, is maybe take a dab of JB Weld and stick it to a screw driver, and press it on the screw till it sets hard, then give it a turn....
Or either that, just cut the outter aluminum around the air screw, till I can grip it with some pliers or something....
Anyone have any spare BS32SS carbs laying around?
(82 GS 650g)
Or anyone know where I can get one at?

One method I have done with success is to use a large cut-off wheel in my Dremel tool to cut a slot down the 'tower' around the screw, then down far enough to cut a fresh slot in the top of the screw. If you cut the slot carefully down the 'tower', the screw will come out very nicely.

Ohhh okay yeah, i was already planning on cutting the tower down some, but i didn't think about just cutting a new slot, i didn't think i would be able to for some reason, i dont know wtf i was thinking, but yeah, thanks!
Im just going to do that, it's pretty much the only option.:clap:

I have some 32mm carbs. Which one do you need?
I can get that screw out but first I'd do as Steve said and cut a new notch in the head and heat it up with a torch. I've gotten many buggered ones out that way.

Don't shorten the tower any, just cut the slot. 
I don't have any pictures of the process handy, but just get the screw aligned so the slot goes sideways,
if possible, then use the cut-off wheel to cut one slot that goes down the tower and into the top of the screw.
When you get the slot cut in the top of the screw, use a new screwdriver so it has a good, fresh tip.

Why not? I have. The Canadian carbs don't even have a tower. Just measure down how far you need to go first. There will still be plenty of threads left for proper adjustment.

Grrrr i still cant get the damn thing started.
The closest thing I got was one small Rumble out of the left exhaust pipe.
(i've been trying for hours)
I tried playing with the choke in all positions.
I tried the petcock switch in all positions.
Im definitely getting gas in the bowls, i checked.
Im getting spark, although the plugs were blacker than black, got them cleaned.
I took the air filter off just to make sure the filter wasnt clogged.
Hit it with some starter fluid, nothing!
I think this has got to narrow it down to Something right?
Maybe fuel pressure related?
-----
Im thinking it has to do with me not benching it before putting the carbs back on the bike?
But if I open the throttle alittle, that would give the same effect as if I DID bench them right?
(because it's allowing air in)

The one that is giving me trouble is #4, it's the one that's furthest on the Rider's Right side.
It's 32mm, BS32SS, 82 GS650g.

Quoting V8 merc, then responding:
I tried playing with the choke in all positions.
No need to "play", just engage it fully. It may run higher than desired until you find the "sweet spot", but it will run.
I tried the petcock switch in all positions.
Use the PRIME position to fill the bowls, the set it to RUN. No need for other positions, unless the tank is almost empty.
Im definitely getting gas in the bowls, i checked.
Verified by pulling the drain plugs? Good.
Im getting spark, although the plugs were blacker than black, got them cleaned.
Black plugs show you are overly rich. Cleaning might not work in marginal situations like this. Get NEW plugs, put them in.
Once the bike is running well, you can put your cleaned plugs in and they should work OK.
I took the air filter off just to make sure the filter wasnt clogged.
Hit it with some starter fluid, nothing!
THROW THE STARTING FLUID AWAY!
Things can go wrong quickly with that stuff, and they are already wrong (or else the bike would be running), so it's not helping at all.
I think this has got to narrow it down to Something right?

The only way to change fuel pressure is to raise or lower the fuel tank.
Keep your tank at the same level it would be installed on the bike.

"Benching" the carbs is the process of ensuring that they all open the same amount at the same time ("synchronizing" them, hence the term "bench sync"). If you do not have the idle speed adjustment set so the throttle blades are open a little bit, you will not be able to start the bike. If you have the "choke" engaged, opening the throttly by hand will defeat its effect, giving problems.
(because it's allowing air in)
When the "choke" is being used properly, it has its own air supply that mixes with its own fuel supply, providing a relatively proper mixture for starting a cold engine.

Alrite guys, got it running!
I changed out the gas and put new plugs in it,.
(I guess the fresh gas I got was already on the brink of going bad, because i've left gas in the tank MUCH longer than that and never had starting problems.)
Tried starting it on Prime a few times, then switched it over to On, she fired RIGHT UP!
Still got some tweaking to do though, she seems to be running rich and the RPM's get really jumpy at random....and the right side of the engine sounds alittle louder than the left.(not quite clanky, but just alittle bit louder.)
But I haven't synced her yet, I have to work all this weekend, so i'll get around to it monday.
But other than that, she is purring really nice! Even without syncing the carbs yet, the bike STILL sounds a hell of a lot cleaner than it did before!
Thanks everybody for helping out, I learned alot!
(even though it was something simple and stupid in the end.
)
Im just glad it wasn't anything major, that's all that matters.
