2008 linhai Yamaha 250 what keep this thing from starting in cold weather? values are set 4 intk 8 ex. enriches working good but it dont fit tight in carb.its loose. carb got gas cant figure it out.this is my first scooter its got 1350 miles on it.once it starts it is hard to keep running. start die. start die. when hit does stay running got to give it throttle or it will die.wont idle till temperature gits 1/2 way or close to it.idle at 2000 rpm.no fast idle or does it have fast idle
