- The Filter Strainer is an attempt to prevent rust and dirt from entering the carburetor.
- The Wrench head plug of strainer was Brass from 1927 - early 1930, and then was steel to the end of production.
- As castings have rusted and eroded, the strainer is not very effective. Much of the fuel flows around the end of the strainer versus through it.
- Filter Strainer is screwed in with a gasket washer using a 5/8" wrench.
