i looked around the site and i found a few posts about my issue but i trouble shooted and still have problems. i kick it over starts right up but after a minute it just revs almost full throttle. i checked for leaks at the jug and head found nothing. tried setting idle screw didnt effect it. checekd my throttle cable and it looked fine, i dont even have to touch the throttle for it to start reving. anyone have any ideas??
