So, we picked up a near mint cr250r yesterday, starts 1 kick with choke, but wont idle without the choke on. I changed alll the fluids, cleaned the carb very well. The jetting is just off in general for the fmf system I believe(fatty, T core 2). any benchmark setting i should start with? Its about 45 degrees by the way, mixed up some fresh 32:1,and cleaned the air filter.
