Some idiot was adjusting my idle but instead of turning the idle screwby the throttle cable turned the screw on the right side of the carb i am guessing is air intake could this casue problems

 

If you are running a S&amp\\;S carb the screw on the right is the accelerator pump adjustment

 

thank you and what exacrly does this screw do or will it harm anything to change this

 

The screw adjusts the throw on the Acceleration pump rod....this adjust the amount of fuel used as the throttle is rolled on. It won't hurt anything but if it's using too much fuel your gas mileage will be down and if it's too little fuel the bike will hesitate wnder hard accleration
