In order to carry out some further tests on the above unit particularly in regard to the durability of the exhaust valve and seat we should like to make the above unit as representative as possible of the B.60 specification. This necessitates schemes and details etc, as follows - (1) Inlet and exhaust cam form and relationship between cams as for B.60. thus deleting the present arrangement of varying the duration and angular relationship between cams. (2) Cylindrical flat bottom tappets as B.60 to be adopted. Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} | ||
