| TO HS. {Lord Ernest Hives - Chair} & BY. {R.W. Bailey - Chief Engineer} FROM R. {Sir Henry Royce} C to BJ. WOR. {Arthur Wormald - General Works Manager} EFG. ORIGINAL R1/M20.9.26. X8680 PHANTOM MAGNETO ADJUSTMENT. " BATTERY " The hexagon on spider of magneto coupling (adjustment part) to be tightened by sheet metal spanner (hexagon 1.2 over flats) and shifter. E73177. C.M 9s/6 oe Also arms of same piece altered to fit standard 3/8" spanner:- BATTERY IGNITION. Cone is too slow- 1 in 4 (?) sticks 20° At this point the spring is not bent correctly to enter between its fixings. Phantom Has the blue high compression/car our latest ignition advance. I found magneto late and battery very early. We altered each quite a lot towards each other and it gave much less detonation. The high compression car should not be shewn until auto: advance improvements fitted. We are going to attack the sticking throttle complaint and fit an improved induction pipe - i.e. Ball bearings on throttle. Increased angle at shut position. Slotted pipe. A temporary cure is to oil the bearings. R. {Sir Henry Royce} | ||
