Just bought a 06 kx250F. It had been sitting for a couple of years. Took the carb in and had it cleaned. Dumped the gnats and debris out of the tank. Installed an in line filter. Have had the carb off 3 times now and can not get it to run with the choke off. Let it idle for 10 minutes. Tried running it up and down the street for awhile and still nothing. Fires up on the first kick and runs fine with choke on but the second you push it in it dies...Any suggestions?
