How do I adjust the idle on a 1998 Mach z?

To adjust the idle on a 1998 Ski-Doo Mach Z, locate the idle adjustment screw, typically found on the carburetor. Start the engine and let it warm up, then use a screwdriver to turn the screw clockwise to increase idle speed or counterclockwise to decrease it. Aim for an idle speed of around 1,200 to 1,400 RPM.
