i took apart the carb. and cleaned it all up, i put a 220 jet in and put the needle on the second clip, one and a half turns on the air screw. after i put it all back together i started it only to have it rev out of control. i don't think there is any air leaks, and the bike was returned to stock that's why i put the 220 jet in, i think it has been bored slightly from a past rebuild, do you think i am running lean? i also wasn't sure if i hooked the floats up to the thingy quit right could that be the problem?
