I need some help. I was given a flywing dt150 that wasn't running. So I put in a new carb and intake and it ran really good. I adjusted the mixture with the screw on the front of the carb by the intake and it was running really well. Then after riding for about 10min i go on a slow turn and the bike dies and fuel come out of the overflow. So I figured it was the floats. Now it is leaking at the screw at the intake and no where else. It's a brand new carb and I dont know what to do with the carb now. I'm new to the dirtbike DIY world. Do I need to do some floats adjustment or what? If i have the fuel off and can pump it about 5-10 times and the bike will run. But as soon as the fuel gets turned on it just poars out from the screw.
