So the dirtbike is running best when the air screw is completely closed. IF I OPEN the air screw a turn or so gas starts to drip out of the drain hose and create a puddle under the swing arm. Can anyone explain this to me? I got a rebuild kit for it. The bike is completely stock except it has uni pod air filter. Which parts do I need to replace to fix this? And will I need to open the carb up in order to fix this or just change jets through bottom plug?
