I figured it is easier to put a new 20usd carb in, then clean the old one. what I did not realize that new carb has no evap connector. this comes from the tank. btw, dumbest thing ever, I see first hand how stupid gov regulations make things more expensive (pretty sure scoot would be 50$ cheaper without this).
so I disconnected everything, and let the hoses hang freely, thing runs great. I suppose this won't cause any problems in terms of performance?
