Air/Fuel Mixture: Adjustments
Idle mixture cannot be adjusted on fuel injected engines. On carbureted engines, idle mixture adjustment should only be performed after diagnosis has
revealed no other faults, or if carburetor has been overhauled. A propane enrichment tool is necessary to accurately adjust idle mixture.
