I finally bought my first 4 stroke. I have had it about 5 weeks, only about 3 tanks used. Last time i took it out, it started up no problem, when i pushed the choke back in it stopped, i could not start it back up again. I have the air screw 2 turns out, clip in 5 position, ride at sealevel in washington state. It always started on the first kick before, i bought the yzf so i wouldnt have to work on it alot, and reliability. Any help would be very helpfull.
