Hi Anonymous, with engine at normal operating temperature idle speed is 950-1050 RPM and air fuel mixture screw (if unsealed) is 1/2-3/4 turns out from bottom, if sealed it's already pre-set. There is a throttle stop screw by the throttle cable ends that with the throttle wide open so the butterfly plate must be perfectly horizontal. Good luck

How do I adjust a Mikuni roundslide carb. Thanks

Turn the air screw and the throttle screw inward until they LIGHTLY seat. Now turn each of them outward one and one half turns. This is the factory setting. You might want to clean the carbs. After cleaning, before you put the slide back into the carb, move the clip on the jet needle downward one notch. This will richen the fuel mix and help with the bog.
