A filtered carburetor cover is temporarily and removably secured to the carburetor throat of a motor vehicle internal combustion engine, for precluding passage of significant amounts of dirt, dust, and foreign matter into the engine intake system while the engine is run. The cover is preferably no larger, or not significantly larger, than the lateral dimensions of the carburetor to which it is secured. The relatively small size of the present carburetor cover allows complete access to the external adjustable components of the carburetor with the cover installed. The cover comprises a generally cylindrical housing having impermeable sides and a porous top, with one or more filtering elements in the top. The filtering elements preferably comprise one or a few sheets of finely woven stainless steel or other metal screen, or a woven synthetic fabric mesh material, for keeping significant amounts of undesirable material out of the engine while it is running without significantly impeding airflow through the carburetor and engine. The present carburetor cover is particularly well suited for use with racing vehicles, where the engines of such vehicles must generally be adjusted and tuned while the vehicles are at race events. The conventional air cleaner used with such vehicles is relatively large, to permit significant airflow therethrough without undue restriction. The large size of such air cleaners precludes ready access to the carburetor thereunder. Thus, the standard air cleaner is removed and the present carburetor cover installed, to permit carburetor adjustment with the engine running.
