How do you adjust the idle on a snowmobile?

To adjust the idle on a snowmobile, locate the idle adjustment screw, usually near the carburetor or throttle body. Start the engine and let it warm up, then gradually turn the screw clockwise to increase the idle speed or counterclockwise to decrease it. Aim for the manufacturer-recommended idle RPM, typically found in the owner’s manual. Finally, test the throttle response to ensure the adjustment is effective.
