03 half throttle start?

I Have A 03 And It Doesn't Like To Start Kick It And Kick IT Three Pump Method Choke Everything, But If I Hold Half Throttle Is Fires Right Up? What Is This

Check your idle screw to see if it is turned in far enough. If it is turned out too far the carb slide will be completely closed and the bike will never start and stay running without holding the throttle open. The carb slide needs to be open some so the intake can draw fuel and air for it to start and idle.

What happened to me was my idle screw was getting hung before it was screwed in far enough to open the slide to allow my bike to start and to idle without holding the throttle open. I discovered this when I had my intake boot off and could look inside my carb and see the slide was completely closed
