It's been holding idle for ~10 minutes. I just revved it and it revs up fine but it "sticks" when it's coming back down to idle.

My '94 acted like that when I bought it in 2008.  The bike ran good but the idle would hang, especially once hot.  I put Marvel Mystery Oil in the gas and ran it.  The problem slowly got better and after many treated tanks went away completely.  My bike now runs like it should all the time.  It's good to be lucky once in a while.

Started to rebuilt the carbs with the kit I bought. I put a new O-ring on the float assembly and now it doesn't seat all the way down, is this going to be a problem? Same with the piece that the float need seals.

Did you lightly oil them so they would slide in?They are tight to keep vibrations from wiggling them loose.I use WD-40 because it will burn through when the engine starts and not cause any problems.Engine oil or 2 stroke oil will work also.

Got them to stay in while I put it back together.
backed the mixture screw out 3 turns on both of them.
Put the bike back together. Idled and revved with no problems. Took it 300 feet down the road and it stalled and then wouldn't start.

I f%$king give up. It's going in the shop, I'm tired of dealing with it. There is nothing left to fix. Carb rebuild, new petcock, clean fuel strainer etc

Have you cleaned the fuel cap?That is how the tank gets air so a vacuum doesn't form as the carbs use fuel.It's a common issue. http://gstwins.com/gsboard/index.php?topic=41061.0

I'll try that tomorrow.

You can test this theory.Set the petcock on PRI.Ride it until it stalls.If it doesn't stall you know it's the petcock.If it does stall.Open the fuel cap for roughly two minutes.Then close it and try to start again.If you're up and running,you know it's the fuel cap.

So keep it on PRI for the entire ride?
The petcock is brand new fyi

Yes, it eliminates it as a problem.The petcock is fine but the vacuum line may have collapsed internally.It happened to my bike after I first got it.Then I converted it to no vacuum.

Tried to take it for a ride to test your theory. Started it up after a bit of cranking. Gave it some throttle and it died. Tried starting it for ten minutes. Would not start. Loosened bowl screws and fuel came out of both. Stumped.

If it's not a fuel issue then it's either electrical or in the ignition system.

Checked spark. Both plugs are firing. Sprayed ether directly into the cylinder head and put the plug back in and cranked it. Nothing.

Prior, I cranked it while holding the throttle wide open for a few times, then pulled the plugs. Dry as a damn bone.

The fuel bowls still have fuel in them and the petcock was set to PRI. 

both plugs might be firing in air but under compression things can change...

Dropping it off tomorrow.
