But right now you just want a fast idle so you can adjust the bike's carb. The idle screw is the screw with a spring on it right that makes contact with the throttle cable.
3) if you have not done so, seat the mixture screw and tun it counter-clockwise (left) 2 and 1/2 turns.
4) let bike run 10 minutes. After bike has remained running for ten minutes, turn mixture crew 1/4 turn to left. wait five seconds, listen for RPM increase. Repeat until rpms do not rise. turn CLOCKWISE 1/2 turn EXACTLY. This is a SLIGHTLY RICH mixture. This is where your mixture should be for optimum performance.
5) set idle using idle screw to 1800 rpms.

i did all that but now the bike does not even stay on? after i changed the carb the bike lasted only 2 days fine and now it doesnt want to stay on, when i let go of the throttle it turns off. too late now, its in the mechanic shop as we speak.
