Anyone know how to go about setting the air and idle screws on the carb? My dumbass had to play around with them and now my Mega Moto 105cc wont start. I tried setting it by 2.5 turns but not sure about the air screw? I tried using the pic from where I got the carb but still not turning over. I did get it to turn over a few times but kept dieing out when I took off the choke or gave it throttle.
