Hello i have a 09 tmec 200. It will not idle properly when cold and stalls when cold. really hard to get it going. After it heats up its fine. To get it to run when cold i need to crank the idle way up. If i use the choke it wont run. The carb is 100% clean, i checked it well. I think it is running too rich. Anyone know how to adjust the carb? Which way is richer and which is leaner? any help is greatly appreciated. PS bike is brand new 40 miles on it.
