Mac{Mr Macintosh} R Wyman noted [Signature] 20/25 Horizontal Carburetter. -------------------------- We send you herewith LeC 4546 showing a modification to the drilling of the petrol holes in the float chamber needle valve seating. These holes are inclined so that they break through on the bottom face and prevent dirt being retained around the needle seat, which can occur when the bottom of the holes break through above the horizontal face.
