frustrated ready to throw in the towel

[ray90813]

I've been racking my brain trying to figure out what I'm doing wrong, the problem with my bike(95 kat 600) is that it idles real low,when I adjust the idle adjustment screw up a little it dies, and won't start till I back it off some. When I have it idleing like that, if I turn the throttle it dies, or let off the choke a little it dies, I checked and cleaned all the jets and ports in my carbs, set the float level, made sure my choke was operating correctly, checked my petcock, everything is within specs, I even went as far as to check my valves and clearance, but the darn thing still has that problem, I know it might be running lean, cause when I add any kind of air adjustment(i.e. throttle)it dies. I replaced the plugs and checked the ignition system, it's ok. Maybe I overlooked something, I'm kind of leaning towards a carb problem, but don't quite know what, it's never been jetted, it's stock, so I don't know, please help, hate to have to send it out.

What did you set the air/fuel mixture screws to? Any vacuum leak?

I set the air fuel mixture screws three turns, and no vacuum leaks, not that I can see or hear, I checked the airbox to carb, carb to engine,vacuum chambers, o-rings, sync ports, caps everything.
