I just got a new winner sport 3. I spent 2 hours trying to start it, and then started to go crazy changing the settings of all 3 carb screws, high, low, and idle. I finally got it started for about 5 seconds and the engine was wound out like crazy and the tires were spinning like mad. Can someone give me some suggestions as to how many turns out (from all the way in) I should set the screws to get it started and stay running for a minute, so I can get to tuning it? THANKS!!!!!!!!
