Needless to say I rebuilt the carb on the old Artic Cat and it runs nice without flooding any more but I want to make sure I have the air mixture screw set correctly. What is the proper method for setting the air mixture on a Mikuni single carb in front of a 500cc Suzuki motor. Is it RPMs, sound, smoke, x amount of turns then rpms?

I'm in minnesota and trail ride moderately but I'm mostly icefishing.

Thanks Pier.

Well Pier good news for you Mikuni carbs are dummy proof. Turn the idle speed screw in until you get an idle a bit faster then what you want. Next turn the idle air screw in till the engine starts to run rough. Next count the half turns and turn the idle air screw out till it runs rough again. In the process of turning the idle air screw out the engine with speed up and run smooth. You counted your turns, now put the idle air screw back in half the amount of turns. Set the idle speed back to where you want it.

Good Luck
