Ok, I rep;aced the slwo jet which helped the bike idle without the use of the choke. That was my first objective. Now, with is started when, I hit the throttle to warm it up, sometimes it revs up, but sometimes it sounds like its trying to kill it. I'll wait 5 seconds and it will rev fine. Wait 5 seconds and then it may sound like its trying to kill it again when I hit the throttle.
