The carburetor needle valve seat is now made integral with the carburetor bowl assembly. This change was necessary, as some owners screwed the dash adjustment rod down so tightly that, when the rod was again opened the needle valve seat turned with the rod. With the new arrangement no damage can result from such practice.

The old style A-9532 carburetor adjusting needle seat and the adjusting needle seat washer A-22086 will be held for service.
