Engine Idle Speed
The best way to assure proper carburetion is to see your dealer for
regularly scheduled servicing, including carburetor adjustment.
Remember, idle speed adjustment is not a "cure-all" for other
problems in your engine's fuel-delivery system. Adjusting the idle will
not compensate for a fault elsewhere.
The engine must be at normal operating temperature for accurate
idle speed adjustment.
For information about high altitude carburetor adjustment, see
page 181.
