Cleaned carb on 1986 TRX250 Fourtrax. Fired it up and idled well for a while. After a couple minutes it started revving itself and when I gave it throttle it would stay at the revs then climb. The throttle is not sticking, I have checked the slide and had a quick look for vacumn leaks. Bike stops revving if you put it in gear. I do not know very much about carbs so forgive me if it's something obvious.
