I'm thinking my CR250 has a problem with the carburetor. I've had it apart, cleaned, checked jets etc, it looks OK. Bike is hard to start cold, I have to kick it 8-10 times. Compression on the bike is good. Also when the bike starts cold, with the choke on, the bike idles real high. When I take the choke off, it comes down quite a bit but still not to where I think it should be. After about 3-4 minutes, the bike idles fairly well, runs good and starts first kick when it's hot. Also, it seems as though fuel is getting on to the outside of the carb somehow, as it is always scummy/dirty when I come back from a ride. Anybody else experience this problem with their 02?
