hi, i have recenly cleaned the whole carby on of my bike to give it a good clean. and im took the air/mixture and tunning screw out. i forget how to adjust the air/mixture screw can anybody give me a idea what it is or who knows it? i would appreciate it alot... i also notice when before i cleaned the carby out i had a problem when i start the bike and pull the choke out it idles fine, but when i push the choke in its like the big revs go up high and higher. and i notice i can't tune the it also, the tunning screw won't help cause its not working when i try to slow the revs down it dosent affect it... the bike is a Yz 80/85 2001 model..
