make sure the slide with the needle is set correctly in the carbOkay so I have some similar issues to a point. I have a Baja 90cc quad and i just completely rebuilt the carb. I have been looking online for a tuning diagram, but I cannot seem to find one. To the point now, I can get the quad started but it has an extremely high idle and if you don't hold the break it will actually start to take off on you. Then when riding it and having it at about half throttle it tends to just bog down and has a bad smell to it. Any ideas?
