ok so this problem is with my 200M. When I try to start it wont but if I take out the air filter it will but it run really crappy and wont idle. its like there is not enough air in the engine. is there a air/fuel mixture screw? the onyy screw I can find is on the right of the carb (if your sitting on the bike) and ive been told that is the idle screw? so does anybody no what my problem is?
