I bought my old blaster back off a friend... They have bored it out, but I am not sure how much. It ran with an air filter when I sold it, but now it does not. My jetting seems to be good, as it idles fine and the spark plug is nice and tan. Can someone please help me? I have posted this question on countless sites and asked a million people and no one can seem to help me. Please help me!!!!!!!
