A carburetor choke plate and air filter assembly for use with a portable rotary power tool. The choke plate is positioned against the carburetor over the fuel-air mixture passage. The plate is secured within the open front end of an air filter housing and is provided with a choke lever to selectively block and unblock the same. The air filter housing includes a side wall portion with a series of air inlet openings formed therein, and internally supports a bent strip of foam type air filter material. An outer end portion of the choke lever projects outwardly through a notch in the filter housing and is sealingly engaged by a front side edge portion of the bent filter material strip. As the lever is pivoted relative to the choke plate, the side edge portion of the filter element strip is deformed to provide a dust seal around the outer end portion of the choke lever in its new pivoted position.
