| RHC.{R. H. Coverley - Production Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. x 6013 Hs{Lord Ernest Hives - Chair}/Wst.6/MA.30.12.32. 3 Per.II Chassis. The ignition distributor governor on this chassis requires modification, before going away, in order to alter the range of automatic advance with speed. To do this new springs are required consisting of 3 turns of 15 SWG. wire set so as to just return the wts to zero. This gives a characteristic as follows :- Commence to advance 1000 R.P.M. Final advance of 11° on distributor spindle at 4250 R.P.M. Will you please arrange for this modification to be carried out. Hs{Lord Ernest Hives - Chair}/Wst. | ||
