Alright so I think I narrowed my problem down....my left carb had/has a slow leak. I checked the float height using Kerry's method and it appears to be too high. I also beleive that I am now running too rich and may have fouled my plugs. I was running
147.5 main, 65 mid, and 22.5 pilot with no washers and stock air/fuel settings. I have a lunchbox and supertrapp full exhaust with 9 discs. It was running good but developed the leak after I rejetted...still ran great....then I decided to turn the air/fuel out to 3 turns. Now it will hardly idle with full choke. Both plugs are black.
I think I might go down to 2 turns....but I am unclear of how to adjust the float height. Please help or offer your input.
well I went back to the 1.5 turns that it has stock and it still idled real low even with the choke on and eventually cut off. my guess is that the floats are too high....what would have caused them to rise since the rejet? and if I bring them back to the right height, are they just going to rise again?

If you know the float height is wrong, you need to take care of that before playing with jetting.
This figure shows the Suzuki shop manual's instructions for adjusting float height:

Pay particular attention to the comment that the floats should be "just in contact" with the needle valve. You will need to lift the float to the point where it is just touching.
