carb adjust/been sitting x 2 years

[jbdrury@aol.com]

I bought an 1988 KLR650 that has been sitting for 2 years. I can't get it to idle. I have: cleaned carb, cleaned jets, bought new battery, changed oil, changed air filter, replaced fuel line hoses, taken apart and put together carb several times. I have main jet screwed in all the way. I tried pilot jet screwed all the way in and also pilot jet backed off one full turn. The bike will start and die out if I try to let it idle. I have played with the idle adjust screw also. I am frustrated. Any suggestions? I am about to give up and declare defeat and take it in to the dealer for service but I really wanted to get this bike running on my own.
