Yes.
Behind the large brass nut is a mesh screen which acts as the filter. These are many times busted or punched out by persons poking into the gas outlet fitting.
Old ones need heat to remove the nut, heat the iron sediment bulb, and then quench in ice or place in freezer, the temp differential of the iron and brass nut usually frees the nut for removal.
Then you can clean or most likely replace the mesh by soldering on a new screen.
