ABSTRACT:
An air filter assembly for an engine such as a chain saw engine. The filter assembly includes a cage, a foam filter having a sidewall surrounding a sidewall of the cage, a retaining member pressing an endwall of the filter against an endwall of the cage and a nut. The nut receives a threaded end of an anchor bolt passing through axially aligned holes in the endwalls of the cage and the filter and a hole in the retaining member. The filter assembly provides high flow rates therethrough and substantially avoids penetration of dirt around the nut connection.
