    Now that I finally got it started, it runs for a few minutes having to apply throttle entire time, but when I come to a stop it dies and won't restart. When I squeeze the clutch it wants to die. whats going on?

    i opened it a little to start then opened it up as I was riding, seemed to get it to run smoother. but after i stopped and it died i tried different positions with no luck. what are the proper positions. cold start, running, warn start etc..?

    except for a cold hard rain or snow on the ground, the choke isn't really needed once the motor has been started a few times since new

    if the idle screw won't get you an idle, then usually, either you're too rich or the clutch is dragging a bit

    how would i fix clutch dragging. If it was vacuum leak why would it run for the first few minutes?

    If it dies right away and wont restart, pull off the float bowl and screw the brass jet back in
