The carburetor includes at least one externally adjustable component. An air filter arrangement of the device is for in-taking air, filtering the air, and directing the filtered air to the carburetor. The arrangement includes a housing. A tamper-resisting portion of the device extends from the air filter arrangement housing and extends adjacent to the location of the at least one adjustable component. The tamper resisting portion includes a segment that permits access to the at least one adjustable component along a first direction and limits access to the at least one adjustable component off of the first direction.
