MINUTES OF TESTERS CONFERENCE HELD ON SATURDAY 6th. APRIL. FRONT END DRIVE. Rm{William Robotham - Chief Engineer}/JRS has got a light cam wheel ready for test which he will run to make sure it is reasonably reliable before next week end, when the engine which is going to be used on endurance will be available. CYLINDER HEADS. Rm{William Robotham - Chief Engineer}/CTS{C. Trot Salt - Carburation} will find out why we cannot have cyl. head HL.273 for test while the rest of the unit is being completed. The programme is that we will repeat on 9.B. the test which was made on 3.B.50. comparing the 2 cyl. heads at 7/1 c/r and at 6 1/2 / 1 c/r.{Sir Henry Royce} in both cases flush top pistons will be used. With regard to the test bed, both lots of heads of 6 1/2 to 1 and 7 to 1 will be compared with the flush top and standard pistons. Rm{William Robotham - Chief Engineer}/CTS{C. Trot Salt - Carburation} will also check running after switching off while he does these tests. CARBURATION. Rm{William Robotham - Chief Engineer}/ym pointed out that he had got poor results from 11.B.V. when he adjusted the tappets down until the valve gear was quiet. The result of decreasing the tappet clearance was to get poor idling and missing on the pick-up. It was agreed that it was time tests were carried out to determine whether the camshaft, which would hereinafter be referred to as the rationalised camshaft, was going to be satisfactory. (Rationalised camshaft = short duration camshaft to EB.4512 with 20 deg. overlap.) In order to establish this point Rm{William Robotham - Chief Engineer}/ym and Rm{William Robotham - Chief Engineer}/TAS{T. Allan Swinden} will carry out tests on 3.B.50 with the latest induction systems now available, and issue a report. IGNITION. Rm{William Robotham - Chief Engineer}/RC{R. Childs} will ensure that 3.B.50 has every | ||
