Ok my son just got a 110 Taotao for a early birthday present. Well this evening he had a little roll over. Well we flipped it back over and he rode it back up to the house and **** it off. After it set for about an hour or a little more he decided to ride some more after dinner. It started up but wouldn't move or idle. The only way it would even move was if I adjusted the set screw for the throttle almost all the way out and he's not experienced enough for that yet! So my question is, what would have caused it to not move or idle after his roll over at where I had the set screw at? Cause before the roll over o had it set perfect for him! Any and all advice is appreciated on where to start or what's wrong with it!
