X7 running rough
So i got a x7 less than a month ago and i got it running after a couple weeks but after some running it ran out so i went to go fill it up again but and just let it be. That was about a week ago and now when i tried to start it, it could start but only if i held the throttle open a little more than idle. Ive used the same mixture in other things like weed wackers with no problem but now all of a sudden the bike just cant idle for more than 30 seconds and when it is idling, it smokes more than usual then dies. I think its running rich but im not the biggest expert on 2 strokes, maybe theres a mixture screw on the carb but im not to sure which screw it is. Its also smelling stronger just to add.
