Idle/Air screw setting

#1
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.

Im not familiar with your engine specifically, but the idle speed is not typically counted in turns out, the air screw is counted in turns. I think your idle is simply set too low. Try 1or 1.5 turns on the air mixture screw and raise the idle. The engine must be hot in order to set the air screw properly so run it for 5 minutes or so once it starts. Good luck.

The screw you are talking about is a fine tuning screw, not something that will prevent an idle unless it's turned all the way in.
