A cover is installed over an engine adjuster such as a carburetor adjustment screw. This cover is in the form of a cap having a flat top with a frangible brim portion. The cap is installed in a housing for the adjustment device, in a recess directly above the adjustment device. An inner rim is formed on the cap beneath the flat top with a recessed portion being formed between the top and the rim. The inner rim of the cap matingly engages a rim which may be formed in the top portion of the adjuster or in a housing surrounding the adjuster and snaps into place joined to either the adjuster or its housing. An anti-pry protective washer or shoulder is provided in the housing. This anti pry device is positioned in close proximity to the outer wall of the inner rim of the cap in a manner to prevent prying instruments from reaching under the inner rim in an attempt to remove the cap. When attempts are made to reach under the cap, the frangible brim portion is likely to break providing evidence of attempted tampering.
