A device for checking random adjustment of the adjustable parts of a carburetor comprising a locked cover or covers mounted over the adjusting screw heads on the adjustable parts so that the cover or covers can not be removed without breaking it. Thus, the device is intended to inhibit the user or "layman" from improperly adjusting the adjustable parts of the carburetor. Provision of the cover or covers is also helpful in preventing the screws from becoming loose under vibration or other external forces.
